You should decompose the image. This is not the only way to do it, but it's certainly the easiest. The Decompose filter was moved in the 1.3 tree to <Image>/Filters/Colors/Decompose. Select RGB from the choices offered, and you will get 3 greyscale images, one for each channel. Cheers, Dave. -- David Neary, Lyon, France E-Mail: [EMAIL PROTECTED]
