radialmind "Hi, I've also recently posted a research note on NDVI and wratten25 on a cmos sensor. Eventually I got my best results by underexposing slightly an..." | Read more » over 8 years ago
radialmind "Chris, thanks very much, those methods are easier. I think now it's time to redo some of the other tests re: the color balance. I want to see the ..." | Read more » over 8 years ago
radialmind "I can't seem to post photos in the comments, so here's some links to my dropbox. This time I dialed exposure down by -1.66. Then I calibrated white..." | Read more » over 8 years ago
radialmind "I agree. I think what the white balance does is basically a custom re-balancing of radiation levels which allows to get correct readings in the end..." | Read more » over 8 years ago
radialmind "Hi Chris, I keep on experimenting here. I got to see the effects of a grey card in sunlight with AWB. I got a nice lila, poison candy picture from..." | Read more » over 8 years ago
