Concerning settings I agree, we can add a checkbox. We could also make the iso
setting start at 0, and disable the shadow/midtones/highlights sliders if iso
is set to 0.

To test DColor::getYCbCr(), DColor::setYCbCr(), you can just remove the call to
randomize to see if we get the same picture. I don't have a decent computer to
test at the moment and I will be busy this week and week-end
