I have some older files that are jpegs that I've been working on and would like to enlarge to about 10x15 for prints. If I make any edits in Lightroom and then want to export to Photoshop for more work, should I be choosing 16 bit or 8 bit in the external editor dialog box? Is there any advantage to letting lightroom bring these into photoshop as 16 bit? Somehow it would seem that somewhere along the way, the programs have to make up pixels, data, create something that isn't there, to do this and I'm not sure if that is desirable. I know that 16 bit is preferred if they are raw files, but what about the jpegs?
