Claim:
1. A method for altering brightness level of a pixel, comprising the steps of: a computer determining one or more brightness levels associated with a first set of pixels within a light source in an image; the computer determining one or more brightness levels associated with a second set of pixels in the image; the computer receiving input to alter at least one of the one or more brightness levels associated with the first set of pixels within the light source; the computer determining an altered one or more brightness levels associated with the first set of pixels within the light source in the image based on the received input to alter at least one of the one or more brightness levels associated with the first set of pixels within the light source; the computer determining a brightness effect on the second set of pixels in the image based on the one or more brightness levels associated with the first set of pixels within the light source and based on the altered at least one of the one or more brightness levels associated with the first set of pixels within the light source; the computer determining an altered one or more brightness levels associated with the second set of pixels in the image based on subtracting the determined brightness effect on the second set of pixels in the image from the determined one or more brightness levels associated with the second set of pixels in the image; and the computer altering one or more brightness levels associated with the second set of pixels in the image based on the received input and the determined brightness effect.
