I went through and processed the pictures from the dancing last weekend, and ended up with 12 "keepers". The files that start with imgp are K100 and the files with lrc are K20. I ended up with the same ratio of shoot/keep with both cameras. http://www.flickr.com/photos/ellarsee/sets/72157621773342262/
Paul, I recognize that a "keeper ratio" in real world conditions is by no means a valid or scientific test of a camera's performance. But, I do find it interesting that in this case I did as well with the K100 as I did with the K20. It occurs to me, that I may have to change my metering technique going from one camera to another. With the K100, I'll generally tweak the exposure so that I don't blow out highlights, and use processing to pull details out of the shadows. However, the area of each pixel on the K100 is nominally 2.5 times that of the K20, so in theory, each pixel has 2.5 times the dynamic range. So, it is possible that with the K20, I need to sacrifice more of the highlights to reduce noise in the shadows. I also note that the objectionable noise on this particular K20 seems to be almost entirely in the blue channel. I have no idea if that is typical, due to the white balance, or the fact that there are fewer blue pixels on the sensor. I would expect that as long as the final image is 6MP or less, then the sensor area per pixel in the final image is approximately the same. For a 3MP (2000x1500) final image the software would average 2 K100 pixels and 5 k20 pixels. -- The first step is learning to take great photos, the second step is learning to throw away ones that are merely good.
