Hi,

I have a question which probably has an easy and straightforward answer…? Anyway:

I have three separate greyscale images, each taken in different wavelengths (red, green and blue). Now, how do I transfer those images into the R, G and B _channels_ in an RGB image? In other words, how do I make a "real-color" image from these three separate grey images? :/

Easy way: Create a new RGB image of the same pixel dimension. Copy each grayscale image and paste it into the appropriate channel of the new RGB image.

Easier way: Use the "Merge Channels" command from the Channels palette flyout menu.

If the images are the exact same pixel dimensions, with all three open choose Merge Channels from the flyout in the Channels palette.
