I want to get into photography and will be getting a new camera soon. After much looking around, I think I'm decided on the Canon Powershot Pro S3. The camera seems to have a lot of features for the price. I would get an SLR, but I want to wait and see how much I get into photography first. Upgrading to an SLR later on if I really like photography isn't a big issue. I plan on using the camera for: 1. night photography and lightning 2. landscapes, skies, and some urban shots. 3. Learning HDR (I already have Photoshop CS2) Is this a good camera for me? Are there any other SLR-like cameras I should look at, like the Powershot Pro S5 or the Olympus SP-550UZ? I also plan on getting this 4 GB SD card and this book and this book for learning photography basics. Is this a good start?
