Digital Canon Rebel XT

I was asked at an art show last summer what kind of camera I used. I am embarrassed to admit I didn’t know. I did know it was a Canon Rebel, but with the new models and similar names (XS, XSi, T1i – I know now because I looked it up) it was confusing and quite honestly I didn’t care that much. I purchased the camera because my uncle is into photography too and he does his research. I’m not much into research and the technicalities of the equipment I use. Is it easy to use? Check. Does it take nice photographs? Check. Can I adjust f-stops, shutter speed, ISO, etc? Check. And I only have one lens for the camera, the 18-55mm kit lens that the camera came with.
