The only way to measure the number of photons is to measure their light. So, it is the same thing. The diaphragm takes care of the extra light to adjust the f number. DanP

I could care less about out favorite troll, I've had him kill-filed for nearly a year now. I'm a big user of CHDK and we have three Canon P&S cameras (one SD800 IS and two A570 IS) that have it installed. I found some of the documentation lacking, and some non-existent, so I wrote it and added it to the Wiki and the FAQ. It's a Wiki, and anyone with useful information can contribute. None of the contributions I have made have been removed or modified, so they appear to be useful to some readers. "http://chdk.wikia.com/wiki/CHDK" When mentioning CHDK in posts, I want to emphasize that it's a volunteer effort, non-commercial, that anyone can contribute their expertise and knowledge to. I don't want people scared off of using CHDK by associating it solely with our favorite troll, so it should be made clear that normal people also are using and contributing to the effort. |
