My wife and I are going on a 9 day vacation trip to Ireland. I normally shoot RAW only with my 1DS. For our trip, however, I plan on shooting both RAW and small JPEG. The reason is that I want to put together a snapshot album of 4"x6" prints of our trip. Anything extraordinary, I would of course use the RAW file, and work on that in P.S. My question is what parameters should I use for the JPEGs so that an inexpensive lab could make nice snap shot 4"x6"s? Since I won't be sharpening, applying levels, color saturation enhancement, etc to the JPEGs, I need parameters applied in-camera so I get good prints without any post processing by me, as I expect I will have a ton of images. BTW, I plan on copying the JPEGs to a CD, and giving the CD to the lab. Any help appreciated.
