Would you need a digital SLR to take pictures of landscapes and people in general? Wouldn't your run-of-the-mill point-and-shoot cameras like Casio Exisilim or Canon Elph with decent resolution (5MP or more) do? I am no professional, heck, I am not even an amateur enthusiast. I just want to take pictures of my gau-ghar, print and post them on my wall. Not a large poster size, just 8" x 11" size. Would the difference between Digital SLR and Point-and-Shoot be markedly different?
