I was planning on buying an XSI or T1I in the next month or so, and am a total noob to camera's and photo editing software. I am more than competent with technology and computers, i just do not have any real experience in the camera and editing fields. First of all, which camera would be better? Would it be smarter to save money, buy the XSi, and use the difference on a better lense? I live in Florida and plan on doing a lot of nature/birds/scenery pictures, as well as sporting events (Gators and baseball). Secondly, is Aperture similar/comparable to Photoshop? Which is better/more user friendly? Thanks!
