These images represent work in progress as I figure out how to present my thesis data.
Comments are welcome.
For 3-color images, I read the single color images into different channels in Photoshop, slide the images around so the different colors register properly, then crop and save to what ever format. The procudure trucolor.pro for IDL works reasonably well as well, since it has good default values for astronomical images. See the last two images on this page for an example.
