Lens Flare effects
You can add rings of light to an RGB image to simulate the flare that appears on a photograph when the camera is aimed towards a direct, bright light. For example, you can create the appearance of sunlight reflecting off a surface or create a space scene with nebulas and galaxies. You can control many elements of a lens flare effect:
•
flare — the brightest part of the reflected light
•
halo — a ring of light that appears around the flare
•
reflection tail — a series of smaller circles moving away from the flare
•
rays — lines of light that radiate from the flare
•
anamorphic light — a streak of light that passes through the flare
You can set the position, size, brightness, and color of these elements, and add noise to create a more natural looking effect.
