To All, Reproduction on-line requires 72 pixels per inch at whatever size you want to display. It used to be that a large image was hard to bring up before DSL, cable and faster computers. the JEPG format is standard for Internet reproduction.
If your going for color magazines they like to receive images t 240 ppi at final repro size. This means that if you submit a image that is sized at 240 ppi and cropped to 5 x 7, it can be used easily at that size or a smaller size. If they want to use it larger you generally have to use some tricks to make that happen properly. If you are using JEPG's it becomes more difficult also. Canon as made a series of cameras called G and I think they are G-11 right now that are great. Nikon just introduced a competing model--I think it's a 5000 something. Both are in the $500 range. Since I've been a Nikon man since HS, I hope to spring for one. The advantage of both these cameras are that they have all the advantages of the cheepie point and shoot but with professional features that you can use or not. Most typical images don't need much editing but I find that I push the limits too often in my work. Overall any camera with above 8 mp should do fine, with 6 being the lower limit. Anything above 12 is usually a waste. Now when it comes to sharpness, that's another ball of wax. Lens sharpness with many of the smaller cameras will peak at mid range--sometimes in the F 5.6 or F 8 range. Unfortunately depth of field with a normal or telephoto setting isn't good enough at 5.6 so you stop down to F 11-22, but you'll loose some sharpness. Too often with modern technology we rely on 'program setting' to do all the work. I find that it normally gets me into trouble so I've seldom us anything but my brain (as long as it holds out)! What I'm doing for increasing depth of field is using a small little part of photoshop CS where you utilize several images shot a different distance settings. It normal works fairly well giving extreme depth of field never possible before. On the downside I've done a few shots where it hasn't worked well enough to be acceptable. At that point I usually have a backup image that is nearly as good.
