I know I can shoot in RAW format with this camera, but I guess I don't know what the use would be... unless I was actually a professional. Perhaps one of you can educated me a bit.  |
If you're uploading directly without first checking the sizes, the photos are probably defaulting at 72dpi, not a good print number(your edges will pixellate even at smaller sizes, like 4x6, which were what mine were at first). Other than a 2x2 inch picture, some pixellating will be noticed at that low dpi, specially red and intricate black and whites. More importantly, a photo at 72dpi, regardless of its size in inches, can not be enlarged(think taking 72 dots and first they're covering an inch(which is pretty spaced out) and you want to print 4 inches of that kind of coverage.Space=blur). WYSIWYG.
With RAW, you can choose your uploaded size, format and dpi before saving to folders with no distortion. It's a pain to work with because it's 'unprocessed' and completely open to your preferences but those are also the strong points of it. But, I would be willing to bet that, if you see the data on the RAW file, it will say 72dpi, so change it to the 250-300 as Daemon stated, before you save the file.

There really is no need or benefit to reading a memory card through the camera other than avoiding cluttering your hard drive. If anything, you're just going to slow yourself down. Basically the camera just acts as a really expensive card reader.

If one doesn't have a reader, the camera is a necessity for that(I don't have any other hardware for the cards). I thought my instructor was confused about my camera, so I tried his way(working off the card) and the 'common' way(uploading to the pc first) and his was a vast improvement. I can print very sharp 11x14" photos(have to be for shows) from a midrange 4mp. Even with my new camera in RAW format, I've gotten to using the card itself and only uploading what's truly finished.
I do the same thing with cards, too, by the way. I don't reuse them, really. I delete what's not necessary, leaving me some extra space, but I always buy new 1g flashcards. I'm thinking I need bigger ones!
