Changing the “Fractal Type” will allow you to generate a variety of patterns – some are blocky, some look like smoke, some look like television static. However, instead of a simple color or gradient, Fractal Noise creates a complex black and white noise pattern on the layer. Much like the Gradient Ramp and Fill effects discussed above, adding Fractal Noise to a layer covers that layer completely. Changing the start and end points of the Gradient Ramp affects where one color stops and another begins. You can use Gradient Ramp to quickly add a bit of visual interest to an otherwise plain background.
Gradient Ramp does the same thing, but uses either a linear or radial two-color gradient instead of a solid color. So, if you wanted to create a silhouette version of a character you were animating, you could pre-compose the character’s layers and apply a dark grey Fill to the resulting composition. Adding Fill to any layer will cover that layer with the solid color of your choice. You can also adjust the radius, intensity, and color of the glow to dial in the exact look you are going for.īoth Fill and Gradient Ramp are simple effects that get used a lot. The “Glow Threshold” determines how bright something needs to be for the glow to appear – so to make more of the image glow, you actually set the threshold to a lower percentage. Adding Glow produces a soft aura around the bright areas of an image. This is an effect that’s easy to overuse, because it often just makes things look cooler. If you want a simpler method of color correcting something, there are also effects for Brightness & Contrast and Hue/Saturation in the Color Correction section – but I think Curves gives the most control.
A small adjustment goes a long way with this effect – dragging a line all the way to the top or bottom of the graph will probably give you pretty bizarre results. You simply choose the channel you want to adjust, then click and drag points on the appropriate line.
Curves gives you control over the color information in an image or video by letting you adjust the red, green, blue, and alpha channels, as well as the overall saturation and brightness. Curves is a simple, but powerful tool that you may already be familiar with if you have experience with photo editing.
