Tim, Stick with the XP2. When you are shooting group pictures of classes, unless you have excellent lighting, you will have some shadows. XP2 Super will allow you to get the photos, and still have an image suitable for scanning. You may want to rate the film at something closer to 200, rather than 400, so that you get good detail in the shadows. Don't worry about the highlights, as XP2 Super can handle them. If you shot the same scene with the Delta 100, you run the risk of the highlights getting too light, making it difficult to scan.(posted 8341 days ago)As for giving the printer prints or scans, ask the printer. Unless you are really good at scanning, and have good equipment, chances are that the publisher can get better results from a print than you will.
