hey - i did a search and came up with nothing, so here goes - ive had a canon s200 for years, and it served my needs. but i'm going to italy to study abroad for the next 4+ months so i thought it was time to get a new camera. i got the canon sd1000, which i read some solid reviews of and was within my price range. now that i've got it, i just have a few questions. i am interested in photography and, in an ideal world, will devote some free time in the future toward learning how to use a dslr. but for the time being, iw as hoping ot make the most of this camera. i read some of the sites commonly linked on this forum about various aspects of the camera, and couldn't quite answer my question. basically, im curious in what circumstances it woudl benefit me to use the highest resolution (what my camera calls "superfine") and the largest image size (3072 x 2304). i've read that for the average user like myself memory card space is a priority over image quality, but card space is not really a concern for me. so, what are the real benefits of these huge and denser images? if they are only going to be viewed and sometimes edited on my computer, is there any reason to make the images larger or denser? i may have answered my own question here, but i remain confused. thanks for your help.
