I take all of the photographs on my blog with a Canon 500D DSLR. I did do an original post when I bought it back in September. I really wasn't sure which camera to get, being a complete newbie with so much to choose from on the camera market it was hard to know which one to choose. Everyone I knew had a Canon and highly recommended them so I headed to Jessops and after help from the Sales Advisor I decided to go with the 500D. At the time I purchased the camera, I also bought a remote, a tripod, and a UV Filter. I bought the tripod and the remote for doing self portrait shots and I'm really glad I purchased them. A UV filter is also a great little thing to have, as it serves a dual purpose in my eyes. In the case that you do leave your lens cap off, you still have the UV filter there to protect your lens, and the main purpose of the UV filter is to reduce haziness that can sometimes be produced by Ultra Violet Light.

In terms of the size of my photographs and editing software I use to add effects to my photos. I try wherever possible to not use the flash in my photos, although sometimes in low lighting this requires a very steady hand. You can really see a big difference in a photograph when the flash has been used. It really bleaches the colours in the photo and doesn't give a true reflection of the colours you are trying to capture. I also resize all of my photos manually before I upload them to Blogger. I use a programme on my Macbook called "Preview" and I adjust the size to 800 x 533. I then upload them to Blogger and select "Original Size."
I use a really old template which allows me to have my images so large, but if you use one of the new Blogger templates, I don't think you can have them so big without altering the HTML and widening your central column. In terms of adding effects to my photos, I never "distort"my photos, so I never airbrush my photos or anything like that. I like to add a vintage effect to some of my shots, or a vignette, and I do this by using various different photo editing software programmes.
So I think that covers everything! If you have any more questions please feel free to ask and I'll try to answer them as best as I can! I hope this has been useful. I can't recommend this camera highly enough, I think its absolutely amazing. I should also mention that it also records HD Video aswell as taking breathtaking photographs.
EDIT: As of January 2012 I also use a Canon 600D.
