[QUOTE="tdodd, post: 1543679, member: 55450"] Stephen, I have openly declared where I have used NR and it certainly isn't in all the images. The swans have no NR (excpt LR defaults). Ditto the butterfly, the blue ball thingy and two of the three images of the pylon. I do not use in camera NR settings and, since I shoot raw and process in Lightroom, any such setting would be ignored. If you want to see comparative examples from a 1D3, 40D and 50D on a like for like basis - identical crop (in terms of subject/composition, not pixels) resized to identical output image size - then please see this online album.... [url]http://picasaweb.google.com/EezyTiger/ResolutionTestLR23CropToSubject#[/url] (Processed in LR 2.3) [URL]http://picasaweb.google.com/EezyTiger/ResolutionTestCropToSubject#[/URL] (Processed in DPP) The images in this album were shot precisely to help me determine which camera produced the best results, from a tight crop, at various ISOs, specifically for bird photography where the subject is small in the frame. The original, uncropped images are in an album here.... [URL]http://picasaweb.google.com/EezyTiger/ResolutionTestFullFrames#[/URL] In my opinion, when comparing images from these cameras on an equal footing the 50D is in no way the inferior performer. Noise is close enough to make no odds and the 50D image has superior detail, at least to my eyes. If you have a raw image or two that you are disappointed with then please make it available and I will happily take a look and draw any conclusions I can. If you can host it yourself then all well and good. Otherwise you can use the free service from [URL]http://www.yousendit.com/[/URL] to "email" it to yourself and then post the link to the file in this thread or in a PM. [/QUOTE]
