Glow effects in Adobe After Effects are more than just digital eye candy. When executed thoughtfully, they become powerful visual tools capable of setting tone, establishing focus, and enhancing storytelling through subtle light cues. Whether you’re designing opening title sequences, cinematic transitions, stylized footage, or immersive animations for music videos, the glow effect acts as both an aesthetic feature and a compositional strategy.
At its core, the concept of glow originates from the natural world. The ambient gleam of a sunset, the fluorescent buzz of a neon sign, or even the quiet shimmer of streetlights on a rainy night of these phenomena can be digitally emulated using glow. This visual simulation becomes especially critical when trying to add emotion, energy, or elegance to a scene. The right glow can elevate a frame from functional to unforgettable.
In After Effects, mastering glow isn’t about piling on brightness about finesse. The glow should serve your composition, not overpower it. A well-crafted glow draws the eye gently, guiding viewers toward focal points. It adds realism in sci-fi visuals, mystery in surreal sequences, and warmth in romantic tones. When synced precisely with motion and lighting, the glow transforms from a superficial highlight to a storytelling device.
The artistic side of glow is intuitive, but the technical side requires precision. Learning to manipulate the built-in glow tools in After Effects ensures you're not only applying effects but shaping them for maximum impact. Before diving into external plugins or advanced compositing, it’s essential to understand what After Effects offers natively and how to harness that with creative intent.
Laying the Foundation: Using Native Glow Tools Effectively
The journey to a stunning glow begins with familiarizing yourself with After Effects' native glow effect, housed under the Stylize category. No third-party installation is required, making it a convenient and reliable feature for any project. Whether you're adding glow to typography, logos, image elements, or video clips, the native effect is both versatile and responsive, making it ideal for beginners and professionals alike.
To start, open Adobe After Effects and initiate a new project. Import your chosen media through the File menu and drag it onto the timeline. This automatically generates a new composition that matches your source’s resolution and frame rate. This setup acts as your visual playground, so take a moment to organize your layers for clarity and flexibility.
Once your footage is in place, navigate to the Effects & Presets panel and locate the Glow effect within the Stylize folder. Alternatively, apply it via the top menu under Effect > Stylize > Glow. Immediately upon application, you’ll see a luminous highlight on the brightest parts of your layer. This default response is just the beginning. The real power lies in customizing it through the Effect Controls panel.
Three primary parameters determine how the glow behavesGlow Threshold, Glow Radius, and Glow Intensity. These settings are the backbone of your glow’s character and demand careful adjustment.
Glow Threshold defines the luminance cutoff. Lowering this value allows more areas of your image to glow, giving a fuller radiance. Increasing it isolates the effect to only the brightest spots. It’s essentially your glow filter, controlling what gets illuminated. This is especially useful when you want to limit the effect to specific highlights without affecting the entire frame.
Glow Radius expands or contracts the spread of light. A larger radius softens the edges and creates a dreamy, ethereal glow that feels more ambient. A tighter radius sharpens the effect, useful for text-based glows or LED-like visuals. Adjusting this helps determine the emotional tone of your glowfrom subtle illumination to bold energy bursts.
Glow Intensity increases or decreases the brightness of the glow itself. High values push the effect toward a more vibrant or aggressive appearance, perfect for electronic or science fiction visuals. Lower values yield a more cinematic or natural light glow, suitable for mood-driven scenes.
You also have options to manipulate the color behavior of your glow. By default, the glow inherits the source layer’s colors, creating a natural blend. However, for greater creative control, switch the Glow Colors setting to A & B Colors. This unlocks dual-color blending and gradient options, allowing the glow to shift dynamically between two designated shades. Using the eyedropper tool, you can sample colors from within your scene for better integration or assign custom hues for stylization.
To fine-tune how these colors interact over time, adjust the Color Looping and Color Phase parameters. These control the glow's rhythm and visual pulsation, bringing an extra dimension of motion and emotion to the effect. Whether you want a slow oscillation or a high-speed color burst, these settings provide the flexibility to sync the glow with your scene’s narrative pace.
Enhancing Animation, Composition, and Creative Application
While applying a static glow may serve certain design goals, animating your glow adds a layer of depth and interactivity. Each of the core parametersthreshold, radius, intensity, and colorcan be animated through keyframes. To begin, click the stopwatch icon beside a parameter in the Effect Controls panel. Move your playhead on the timeline, change the parameter value, and After Effects will automatically interpolate the transformation between keyframes.
Animating Glow Intensity can simulate flickering lights, electrical surges, or magical build-ups. Adjusting the Glow Radius over time can give the impression of fog-drenched headlights or glowing energy fields that expand and contract. When combined with scale, opacity, and motion, these animated glows help establish atmosphere, timing, and emotion in dynamic ways.
For more precise and polished results, use the Graph Editor. This tool allows you to adjust the speed and timing of your keyframes with Bezier handles. Applying ease-in and ease-out curves results in more organic, natural motion, ensuring the glow fades or builds in a way that feels fluid and believable. Attention to this detail often separates professional-quality motion graphics from basic ones.
A smart workflow trick is to apply the glow effect on an adjustment layer rather than directly on your footage. This method offers several advantages. First, it keeps your original media untouched, allowing for cleaner edits and easier reversibility. Second, it provides better flexibility when combining the glow with other effects such as Gaussian Blur, Curves, or Tint. You can also control the glow's visibility and blend mode independently, making it easier to test different creative directions without affecting the underlying composition.
Layering multiple effects with glow can yield exceptional results. Adding a Gaussian Blur can increase softness, especially for a dreamy or cinematic look. Using the Curves effect allows you to adjust color balance and contrast in the glow layer specifically, helping it harmonize with the scene’s overall tone. Introducing a subtle Camera Lens Blur adds realism by simulating how light scatters through camera optics.
Previewing your work frequently using the RAM Preview feature is crucial. Static frames only tell part of the story. Glow behaves differently during motion and transitions, and you’ll often catch flickers, oversaturation, or misplaced timing that only become apparent during playback. Evaluate your animation in real time to ensure seamless visual integration.
When crafting glow-heavy scenes, it’s also wise to monitor your system performance. Glow effects can be render-intensive, especially when used in large compositions or stacked with other effects. Optimize your workflow by pre-rendering glow layers or using proxy files during editing.
As you explore more complex compositions, consider combining glows across multiple layers with varying blend modes and opacities. This can help simulate depth and parallax lighting, where glows react as the camera moves or elements pass in front of each other. Multiply or Add blend modes work especially well to merge light-based elements realistically.
Ultimately, achieving professional-level glow in Adobe After Effects requires both technical knowledge and artistic sensitivity. From animated neon titles to mystical auras, the glow effect opens up a realm of possibilities when used thoughtfully. Mastering its nuancesbalancing luminance, integrating with motion, syncing with soundtracks, and harmonizing color palettes allows you to infuse your visual storytelling with atmosphere and intent.
Elevating Glow Effects in After Effects: Introducing Precision Lighting Techniques
Creating glow effects in Adobe After Effects has long been a standard visual enhancement technique, commonly achieved using the native glow features. These built-in tools are useful for quick edits and broad visual stylizations, but when you’re seeking advanced control and cinematic finesse, they can quickly feel limited. That’s where external glow systems come into play. Part two of our glow enhancement series takes a deep dive into a professional-grade glow method that offers a richer set of tools, creative accuracy, and seamless integration into dynamic compositions.
To get started, open After Effects and import the desired footage or still layers you want to work with. Create a new composition or load an existing project that’s ready for enhancement. Make sure your layers are organized within the timeline and adjust their hierarchy with precision, especially if you’re planning to build composite scenes. Understanding how these layers interact through blending modes will prove essential as you begin shaping the glow effect around your elements.
Next, apply the third-party glow plugin by selecting the layer you wish to modify. You’ll find this external effect categorized under lighting tools in your Effects panel. Once applied, you’ll immediately see the default glow appear on your footage. However, the real creative power lies in the plugin’s integrated FX Editor, which brings up a completely separate editing interface designed specifically for in-depth glow sculpting. Click the FX Editor button within the Effect Controls panel to launch this environment.
This editor features a dual-pane layout. On the left, you’ll discover a well-curated collection of presets. These serve as both time-savers and creative inspiration. Choose from glow types that resemble warm halogen lights, soft atmospheric haloes, vibrant surreal tones, or industrial-style neon flares. Once you’ve picked a preset that aligns with your artistic direction, you can move to the right side of the interface to fine-tune every aspect of the glow effect.
Fine-Tuning the Glow: Customization Tools and Realistic Light Behavior
At the heart of this plugin is a sophisticated glow engine that mimics real-world light behavior. Unlike the basic glow function inside After Effects, which primarily increases brightness around light areas, this advanced tool gives you the ability to sculpt the glow’s appearance with high precision. The brightness control is your starting point. Dialing this up or down determines the intensity with which the glow radiates outward. Use higher values for bold, spotlight-style effects and lower values to achieve subtle, ambient light overlays that enhance without overpowering.
Equally important is the softness control, which governs the spread and feathering of the glow’s edges. A low softness value keeps the glow tight and defined, while higher values expand it into the surrounding pixels, creating an ethereal diffusion effect. This kind of visual treatment is especially powerful when trying to emulate cinematic lenses, such as those found in atmospheric or dreamy film scenes.
Blending modes within the plugin take compositing further than what the standard After Effects toolset provides. While additive and screen modes are both available natively, the third-party system allows for an expanded range of blending methods that respond dynamically to surrounding pixel values. This lets you integrate your glow more naturally into multi-layered environments, giving your scene a more cohesive lighting narrative.
The glow effect doesn’t operate in isolation. Built into the same plugin are robust color grading options that help you tailor the glow to match your footage’s tone. Adjust hue rotation to shift the color angle, tweak saturation to deepen or soften the vibrancy, and refine brightness and contrast levels to balance your lighting against the rest of the scene. You can also change the color temperature, either warming the glow with golden tones or cooling it with icy blues. For an even finer degree of color accuracy, individual red, green, and blue channels can be amplified or reduced independently, offering true chromatic control.
But the plugin’s most innovative feature lies in its ability to isolate glow effects to specific areas within a frame. Using the matte controls, you can ensure that only certain parts of the image are affected by the glow, leaving the rest of the layer untouched. This is an essential capability for scenes that require targeted highlights, such as glowing signage, facial light accents, or graphic overlays that demand precision.
To activate the matte function, switch the viewing mode to Matte. The visual display shifts into a high-contrast black-and-white view, where white represents the areas currently influenced by the glow. By adjusting the matte’s range sliders, you can expand or contract the active zone. Add blur to the matte edge to create a gradual transition between glowing and non-glowing regions, achieving a natural falloff that enhances realism.
Isolating and Tracking Glows: Advanced Masking with Mocha Integration
For creators working with footage that involves camera movement, object motion, or dynamic perspectives, the plugin offers an advanced feature that significantly extends its utility. This is where integrated motion tracking and masking come into play. With a single click from the effect panel, you can launch a dedicated masking interface powered by a built-in planar tracking system. This system allows you to draw custom spline-based masks around specific subjects or elements in your scene.
Using pen tools or x-spline shapes, trace the areas you want to glowsuch as a subject’s eyes, light-emitting props, or specific sections of a user interface element. Once your shapes are created, initiate the tracking process. The system supports motion types including translation, scale, rotation, and even perspective shifts, meaning it can follow your mask shapes through complex 3D camera moves or object transformations.
When tracking is complete, the shapes remain locked to the movement of the targeted elements, ensuring the glow effect remains consistent and natural throughout your scene. You can return to the main After Effects interface and head to the Pixel Chooser section of the plugin, where the mask intensity and blend style can be further refined. Feather the mask edges to soften the transitions, adjust opacity to reduce harsh lines, and experiment with light blending modes to perfect the glow’s integration with the moving footage.
Combining this tracking capability with the glow and matte controls empowers artists to create highly surgical lighting effects that remain stable and visually believable even under challenging motion scenarios. Whether you’re animating a glowing user interface on a moving device, creating a mystical aura that follows a character’s eyes, or simulating glowing indicators on rotating machinery, this toolkit allows for pinpoint accuracy.
This level of control makes it possible to build glow effects that are not just visual overlays but integral components of the lighting and emotional tone of your scene. By blending color grading, mask refinement, and motion tracking into a unified workflow, you are able to craft lighting that feels like a part of the physical space captured on camera. No longer restricted to static glows that simply brighten pixels, your compositions can now feature glowing elements that react intelligently to scene motion, context, and emotional mood.
In practice, this advanced glow workflow enables you to move beyond basic lighting and into the territory of visual storytelling. Use glowing elements to guide the viewer’s attention, build ambient lighting that reflects the tone of the scene, and subtly reinforce your narrative through the interplay of light and form. Continue refining your technique by exploring different preset combinations, experimenting with mask shapes, and leveraging tracking data to achieve cinematic polish.
The glow becomes more than an effect, becoming a tool for atmospheric and emotional impact. With each layer of refinement, you bring your scene one step closer to the lighting sophistication of high-end film production. Embrace the power of advanced glow design and transform your After Effects projects into visually arresting cinematic experiences.
Breathing Life into Glow: Foundational Techniques for Animating Light in After Effects
Glow effects in Adobe After Effects are a staple in visual storytelling, whether you're crafting music videos, cinematic sequences, or motion design projects. While applying a static glow can be visually pleasing, real magic happens when you begin to animate those glowing elements. Animation introduces rhythm, emotion, and narrative flow, turning simple visuals into expressive, living designs. In this phase of your creative workflow, we focus on taking glow beyond still imagery, exploring how to bring it to life with motion and dynamic interaction.
Start by opening your After Effects project and identifying the layer where your glow has already been applied. Within the Effects panel, most parameters associated with the Glow effect can be animated, thanks to their keyframe-enabled stopwatches. This includes key properties such as Glow Intensity, Radius, Threshold, and Color settings. Begin your animation process by selecting the Intensity parameter and clicking the stopwatch to activate keyframes. Move the playhead forward in the timeline and adjust the intensity upward to simulate a gradual light flare. This creates a basic but effective visual cue of something awakening or powering up.
To deepen the impact, don’t treat intensity in isolation. Bring in the Glow Radius parameter and animate it in sync with the intensity. As the intensity increases, allow the radius to expand outward. When the intensity fades, reduce the radius accordingly. This subtle but powerful interaction creates a breathing light effect, much like neon signs flickering with life or sci-fi energy pulses ebbing and flowing in a rhythmic pattern. This interconnected animation is perfect for everything from futuristic UI elements to magical visual sequences.
You can further enhance emotional depth by animating the glow's color properties in tandem with intensity. Color has a profound psychological impact. Warmer tones like red, orange, or golden yellow convey energy, warmth, and vitality. Cooler tones, such as blue or purple, on the other hand, evoke calmness, mystery, or melancholy. By shifting color values during intensity transitions, your glow can mirror the mood of your scene. For instance, if a character experiences a revelation or emotional climax, a glowing shift from cold to warm hues can visually echo that transformation.
Advanced Motion: Expressions, Audio Sync, and External Tracking Techniques
Once you’ve mastered basic keyframing, you can take your animations to the next level by incorporating expressions. Expressions let you inject dynamic behavior without setting keyframes manually. A classic and effective example is using a wiggle expression to make your glow appear unpredictable, flickering like a failing fluorescent bulb or an enchanted artifact. This causes the intensity to shift randomly twice every second, within a range of 0.3 units. You can tweak these values to match the pace and volatility of your scene.
For scenes involving music or sound-based visuals, a powerful method is syncing glow properties to audio. This technique is particularly effective in music videos, nightclub visuals, or interactive installations. Begin by importing your audio track and right-clicking it to select Keyframe Assistant and then Convert Audio to Keyframes. This generates a new layer containing amplitude data. You can then use pick-whip linking or expressions to connect the glow’s intensity to the amplitude of the audio track. The result is a pulsating glow that reacts in real-time to beats, drops, and crescendos, effectively transforming your visuals into a harmonic light show.
For projects that use an external glow system with built-in motion tracking, animating glows becomes even more immersive. One of the most valuable techniques is integrating planar tracking into your glow animation. Consider a scene where a character walks through a dark alley wearing a glowing amulet. To make that glow stay perfectly anchored to the moving amulet, use the tracking system to mask the amulet and track its motion across the footage. Apply the tracked data to a null object, and then link the glow parameters to that motion. You can even animate the glow’s intensity to rise as dramatic tension builds, subtly underscoring narrative beats with light.
Complex motion can also be achieved by duplicating your glow layer and animating each one slightly out of sync. For instance, duplicate your base layer several times, apply different glow settings to each, and then animate their intensities at staggered intervals. This layering technique produces a more kinetic and textured visual effect, which is especially compelling in abstract motion design or futuristic environments. With careful timing, the glow feels alive, echoing the look of electric circuitry, cosmic radiation, or interstellar travel visuals.
Scene Integration: Adjustment Layers, Motion Blur, and Cinematic Flourishes
To unify glow effects across multiple layers or objects, use adjustment layers creatively. An adjustment layer allows you to apply a single glow animation to everything beneath it in the layer stack. This is perfect when you want to control the glow intensity or hue of an entire scene. Begin by creating an adjustment layer and applying your glow effect to it. Animate key parameters like intensity or radius over time. Then, fine-tune the blending modes and opacity to blend the glow smoothly with your footage. You can also crossfade between multiple versions of glow animations by layering adjustment layers and keyframing their opacity. This technique is particularly effective for transitions or dreamlike sequences.
Motion blur is another vital enhancement when animating glows. It’s easy to overlook, but motion blur can be the key to making your glowing elements feel truly integrated into the scene. When a glowing object moves rapidly, it should leave a subtle trail of light, mimicking the natural behavior of bright light in motion. To enable this, first activate motion blur in your composition settings. Then, toggle the motion blur switch for each relevant layer. Once enabled, any rapid motion of your glowing element will produce a soft trailing effect, reinforcing the illusion of luminosity and speed.
To take things even further, introduce light flares that accentuate glow transitions. Light flares are excellent tools for punctuating moments of transformation or energy spikes. You can build them using shape layers, combining ellipses with feathered masks and Gaussian blur. Animate their scale, opacity, and rotation in sync with your main glow parameters. A well-timed light flare that peaks as the glow reaches maximum intensity adds cinematic polish and emotional impact. These effects work beautifully in fantasy scenes, high-tech UI graphics, and energetic logo reveals.
When combining all of these techniquesmanual keyframing, expression-driven behavior, audio-reactive pulses, advanced tracking, and post-process enhancement build a visual language that speaks far louder than a static design ever could. Every motion, flicker, or hue shift contributes to the overall mood, pacing, and narrative weight of your animation. The glow becomes more than an effect. It becomes a character in your story.
By mastering the art of animating glow in Adobe After Effects, you give yourself the power to transform light into an expressive tool that guides your viewer’s focus, elevates your storytelling, and brings your compositions to life. From gentle flickers to explosive flares, every animated glow carries meaning and energy. Let it evolve, sync it to your audio, track it across movement, and layer it with intention. With the right techniques and a thoughtful approach, animated glow effects can be the highlight of your creative work, literally and figuratively.
Elevating Your Glow Effects: Composition, Color Harmony, and Realism
Once you’ve created and animated your glow, the next major step is ensuring it feels like an organic part of your visual world. Mastering glow effects in Adobe After Effects doesn’t stop at merely adding lightit requires integrating that light seamlessly into the narrative of your scene. The finishing phase is where the illusion becomes convincing, and where light stops being an effect and starts becoming emotion, atmosphere, and storytelling.
Begin by stepping back and assessing your glow effect in the broader context of your full composition. Ask yourself: is the glow drawing attention to the correct focal point? Does it reinforce the lighting already present in the environment, or does it appear artificially pasted on top of the scene? These questions are crucial when you're aiming for a high-end look. Effective glow must feel native to the environment. To achieve this, visual consistency is essential, and that starts with refined color correction.
Tools like the Curves effect and Lumetri Color panel are invaluable here. Use them to color-grade your glow so that it matches the surrounding lighting temperature and color palette. If your scene is bathed in warm sunset tones, a harsh neon blue glow may feel disconnected. Subtle hue shifts and saturation adjustments can allow the glow to blend in, making it look as if it belongs. A good rule of thumb is to pull references from real-world lighting scenarios or film stills to ensure your light source behaves believably in its digital context.
One of the most overlooked aspects of realistic glow integration is depth. Scenes feel more immersive when glows react tothe depth of the field. In After Effects, simulating depth is possible through camera blur effects or compound lens blur. If your main subject is sharply in focus, but the glow resides in the background, blurring it accordingly can create a layered, cinematic feel. It draws the eye naturally, providing dimensional separation between elements and reinforcing depth cues that the human eye expects.
Realism also comes from interaction. Consider how your glow affects the surrounding environment. Is it casting reflections or subtle illumination? While After Effects doesn't calculate real-time light bounces, you can manually simulate these effects. One method is to duplicate the glow layer and transform it to reflect against virtual surfaces, such as floors or glass panes. By reducing the opacity, applying a heavier blur, and adjusting the tint to be slightly darker, you can suggest light spill or reflection. This approach enhances believability and adds polish to the final output.
Creating Atmospheric Depth: Light, Texture, and Movement Integration
The secret ingredient in many high-end visual compositions is atmosphere. Great glow effects don’t just shine, they breathe. Introducing environmental layers such as fog, light rays, and lens textures can elevate your glow from a flat visual gimmick to an immersive element that contributes to the emotional tone of the scene.
For example, adding a subtle fog overlay across your scene can diffuse the glow slightly, giving it a soft, ethereal quality. Similarly, light rays that spill from the glow source can hint at dust or volume in the space, making the light feel more physical. These effects can be achieved through procedural generation inside After Effects or by compositing high-quality stock overlays. The key is subtlety. Adjust blending modes such as Screen or Add, and reduce opacity so the effect is felt more than it is seen. The goal is not to distract from the main content but to enhance the visual experience with atmospheric richness.
Lens dirt is another layer that can sell realism. Just as real camera lenses accumulate grime and micro-particles that catch bright light, you can replicate this look digitally. Overlaying lens textures and syncing them with the brightness of your glow can suggest the presence of light flares bouncing around inside the camera. It’s a small touch, but one that brings a tangible authenticity that resonates with viewers subconsciously.
In compositions that utilize 3D layers or 3D cameras, anchoring your glow in the spatial environment becomes crucial. Simply put, your glow needs to move believably in 3D space as the camera shifts perspective. Parenting the glow to a 3D null object ensures that it maintains consistent spatial relationships within the scene. This integration is essential in motion graphics or visual effects-heavy scenes where the camera movement adds drama or perspective.
Motion itself can also amplify the glow. In rhythm-based or audio-reactive visuals, linking glow intensity or presence to audio cues creates a visceral, synchronized effect. Within After Effects, you can generate audio markers or use expressions that tie glow intensity to specific beats or frequency ranges. This approach is particularly effective in music videos or branded content where visual energy needs to track with sonic energy. With glow pulses triggered on key beats, your visuals become rhythmically alive, adding a layer of interactivity between what’s heard and what’s seen.
Smart Workflow Techniques: Global Control, Testing, and Artistic Intuition
When managing complex compositions with multiple glowing elements, controlling each individually can become tedious and error-prone. A professional and efficient technique is to build a centralized glow controller. This involves creating a dedicated null object and adding expression sliders for core glow parameters such as intensity, color, and spread. By linking multiple glow effects across different layers to these sliders, you gain the ability to make global adjustments instantly. This method not only saves time but ensures visual consistency, especially when working across large timelines or collaborating in team environments.
As you near the completion of your project, it’s essential to perform comparative render tests. Render your scene both with and without glow layers activated. This comparison allows you to critically assess whether the glow is enhancing the narrative or simply adding visual clutter. Glows should never overpower your composition or distract from the message. They should complement, highlight, and guide the viewer’s eye intuitively.
Post-production is where your artistic judgment becomes paramount. Technical execution lays the foundation, but visual storytelling guides the final decision-making. Trust your eye. If a glow looks too strong, pulls focus away from a key subject, or breaks continuity, tone it down or rework its interaction with the environment. Sometimes, a barely-there glow does more storytelling work than a blazing neon pulse.
Remember, glow is more than just a digital light source’s a visual language. It communicates emotional temperature, time of day, energy level, and narrative emphasis. Whether it’s used to add spectacle to a high-energy sequence or to underscore the soft mystery of a quiet moment, the glow becomes part of the scene’s visual vocabulary.
Conclusion
Mastering the glow effect in After Effects is a transformative skill that elevates your creative projects. By understanding the fundamentals of glow manipulation and exploring advanced techniques like motion tracking and audio synchronization, you can craft stunning visuals that not only captivate but also deepen your storytelling. Glow is no longer just a visual toolit’s an emotional and atmospheric language that enhances focus, rhythm, and mood. With thoughtful application and precision, your glow effects can breathe life into every frame, turning ordinary scenes into cinematic masterpieces. Harness its power to amplify your creative vision and bring your compositions to life.
