I have an 8 megapixel Canon EOS Rebel XT. It is a very good camera, but I notice that when I open images in my editing program that the resolution of the images is always 72 pixels. The size of the image is huge - 3456 X 2304 - but how can I increase the resolution? Any tips on getting sharper images would also be appreciated. Thanks.

I purchased the Canon EOS Digital Rebel XT 8 MP about a week before christmas and I’m SO in love with it.
I love the details of the picture, but I’m curious to know if they could become better in any way.
People have been telling me that lenses would make the quality better?

I would like the image to look sharper, crisper, better?
And I really wanna do some macros!

Do you have any tips on lens or any other accessories that would help my photos?

Thanks!
