Boosts or lowers the uniform brightness of an image by a specified amount.
Although this may seem to be the first filter to use for correcting for improper exposure in an image, Brightness boosts or lowers everything in an image at once. This means that raising the brightness in an image raises brightness everywhere, including in the shadows. Consequently, a brightened image may look washed out.
However, this filter is useful for modifying the edges and effects of shapes, masks, particle systems, and generators.
A better filter for exposure correction is the Gamma filter.
Adjust this filter using the parameter controls in the Filters Inspector:
Brightness: Sets the multiplying brightness value applied to the image.
Mix: Sets the percentage of the original image to be blended with the color-corrected image.
