Camera manufacturers keep on upping the ante with how many MP their cameras have, and for a while I believed that it was silly, who cares if it has 10 or 12. But lately I have decided that I could use the extra MP. For one, it is invaluable when cropping and making big prints. Using my Canon S5, I get 2448 x 3264 resolution, which seems like a lot. But lately I decided to print out some 8x10 prints. I like prints done at 300 dpi. So that leaves me with almost no space to crop, because if I go under 2400 x 3000 I will get a reduction in image quality. Also, I just sent away for a 2000 piece 28 x 35 inch puzzle. They print at 150 dpi. Even without doing any cropping I don't have enough resolution the get the best quality. Ok, I understand that more MP on the same size sensor can reduce IQ, and I don't want that. But once they solve that I want a 20 mp shooter or more. With 4 gig sd cards at just a few dollars, and budget laptops coming with 250 gb hard disks, there is no reason not to.
