Light and Shadow Filters Description
Supernova Long arcs of light that radiate from the centre of a supernova attempt to produce
a flare. The most common options for this filter are color, the radius of the center,
the number of rays or spokes, and a setting for random hue that produces an effect
resembling a rainbow in the light ray.
Lens Flare & Gradient Flare They recreate sun-like flares in images by adding lens-like effects to gradients, which
they call lens flare and gradient flare.
Lighting Flare This is a potent instrument for producing effects resembling those of studio lighting.
Spot lighting is one way to use this tool to draw attention to particular areas of the
picture. The default parameters take into account both point lights and directional
lights. Other settings include those for exact positioning and glowing, for intensity,
and for bump & environment map.
Sparkle It uses a series of tiny flare effects to highlight specific areas of the current picture
to produce the sparkle effect. With this utility, you can change the hue, saturation,
and transparency as well as the threshold, intensity, spike length, points, and angle
orientation.
DropShadow You can give a picture, a selection, or a text a drop-shadow. The shadow’s hue,
location, and size are all customizable.
Long Shadow It makes it easier to make long shadows in a variety of visual designs. The chosen
layer must have an alpha channel in order to use this filter.
Vignette Vignetting in photography is a decrease in picture brightness towards the periphery.
Due to camera settings or lens restrictions, it is frequently an undesirable result.
However, it is also purposefully used to highlight the image’s focal point.
Drop Shadow (legacy) This filter applies a drop-shadow to the active selection or to the entire image. If
required for displaying the shadow, the filter may optionally resize the image. The
shadow’s hue, location, and size are all customizable.
Xach-Effect This filter gives the chosen area or alpha channel a soft transparent 3D effect.
