Also when manipulating the 3D images later with an image processing application you should be very careful not to change the colors.
In RedGreen you can create monochrome and color 3D images. Both images can be viewed with the three kinds of 3D glasses (red-green, red-blue and red-cyan). But only with red-cyan glasses you can profit from color images (with red-green and red-blue glasses you'll only get a monochrome impression of color images). But in some cases you may get better results when creating monochrome 3D images even when using red-cyan 3D glasses. This can happen if certain details of the original image will result in a very different brightness in the resulting 3D image for the left and right eye. This can be irritating. Creating monochrome 3D images will always result in a well balanced brightness for the left and right eye. When only using red-green or red-blue 3D glasses you should always create monochrome images to make sure that you'll always get a balanced brightness for both eyes.
