How can I capture grayscale images from an RGB camera?
There are two methods for capturing grayscale images from an RGB camera. The first is to simply capture from the green signal (source 2 in the ‘Video Control’ dialog box). The green signal contains the majority of the grayscale information of a color image. The second method is to use Image’s ‘Capture Color’ command. After the three color slices are captured, choose the ‘RGB to 8 Bit Color’ command with the existing palette option selected. If you were currently working with a grayscale look-up table, then the resulting image will be the correct grayscale image.
