I have 400 shots (taken RAW on a D90) and want to output them to JPEG from within Aperture. The shots are to be viewed on a computer screen, maybe some used for a Website, and I guess a few might need to be printed. Some are cropped, and so the sized vary between 5MB and 10MB. Is there a way to process the shots to get them all to output around a similar file size? I was thinking to make them, say, 5MB so as not to lose too much quality.
