I shot into the middle of the room. The 1Ds MkII was set at H (3200 ISO), 2 stop under exposure compensation dial in. I opened the image in Camera Raw, did almost nothing to it, brought it into Photoshop, resized it to 900 x 600 and saved it as a jpeg: <http://www.adambridge.com/Photos/2006/02/01/_L3U8867.jpg> Then I took the original photoshop image and cropped out the middle so you can see a full-pixel rendering and saved it here: <http://www.adambridge.com/Photos/2006/02/01/_L3U8867-actual pixels.jpg> Remember - these are PURE files with no sharpening, noise reduction, nada. The effective ISO should be about 12,000. The room is quite dark. The "glow" on the back wall by the window is not observable to the naked eye. The wall appears with no light gradient at all - a constant surface at least to my eye. You can look at the EXIF data and see exposure 1/30 s at f/2.8 (wide open). Maybe this isn't a fair test and I should do a portrait but my wife is in a meeting and I was too lazy to set up a tripod.
