I have a number of JPEGs in grey color profile. This is how the images are saved (the images are digital x-rays). I would like to annotate the images and I use Preview for that. When I save the annotated images the color of the text reverts to grey since image color profile is grey. I need to change them to RGB profile. How can I do that using iphoto or any other software that came with my MacBook Pro? During my one to one session, my trainer suggested importing image into the Keynote, saving it and then exporting it. It comes out with an RGB profile, however, I need to do this with tens and sometimes hundreds of images (x-rays) and importing each one into keynote is not very efficient. Is there a way to batch converting them from grayscale to RGB? Thank you for your suggestions.
