Changing Image Channels from 1 channel to 2

Hi everyone,

I am currently working with aggrecount and am having trouble changing my 1 channel rgb image to a 2 channel 16 bit image. Does anyone know how I can do this?

Thank you for your help!

Hello bd6376 (How do you pronounce that?),
You can convert the image to 16 bit, then use a two color LUT on it. Once applied convert back to RGB and then split colors.
