Canon EOS Rebel T1i / 500D Review and Sample Photos at DCResource – A nice touch at DCResource is the inclusion of a review of the software that comes with the camera.

Jeff Keller notes the following with regards to image quality:

Photo quality has always been a strong point of Canon D-SLRs, and that’s generally true with the T1i. The Rebel T1i takes well-exposed photos, though it does clip highlights a bit more than I’d like. Colors were pleasing the majority of the time, except with the night and indoor church shots, which had noticeable brown color casts. As with other Canon D-SLRs, images straight out of the camera are on the soft side. You can bump up the in-camera sharpening by using the Picture Styles feature if you think so too. The camera keeps noise levels very low — you won’t have an issue with it until ISO 1600 in low light and ISO 3200 in normal lighting. Higher sensitivities are quite usable if you don’t mind shooting RAW and post-processing a bit. Like with its predecessors, the Rebel T1i has a bit of redeye problem, and there’s no way to remove it on the camera. Purple fringing levels were fairly low.

There’s also a gallery of full-resolution image examples for you to assess the output quality of the T1i / 500D with.
