Canon Digital Rebel XSi Digital Camera Review

Picture Quality / Size Options (8.50)
The XSi provides eight options for setting the combined image size and quality, detailed below:

Image Size/Quality Settings
Large, high quality	12 Megapixels (4272 x 2848)
Large, normal quality	12 Megapixels (4272 x 2848)
Medium, high quality	6.3 Megapixels (3088 x 2056)
Medium, normal quality	6.3 Megapixels (3088 x 2056)
Small, high quality	3.4 Megapixels (2256 x 1504)
Small, normal quality	3.4 Megapixels (2256 x 1504)
RAW + Large	12 Megapixels (4272 x 2848), saves both RAW and high quality  JPEG
RAW	12 Megapixels (4272 x 2848), RAW only

For each of the image quality modes above, the XSi also provides an estimate of the number of files that should fit on the inserted card. For a 2GB SD card, the estimate is 355 in the large high-quality mode and 109 in RAW mode.

Picture Effects Mode (1.0)
There are no specific tools for editing images after they are taken on the camera, except for the ability to rotate. If you are printing to a PictBridge printer, you do get some limited options for cropping and changing colors, but this is done by the printer, not the camera. Frankly, most users won't miss things like on-camera cropping and being able to add fancy borders; these things are best done using an image editing program on a computer.
