i've seen some people ask how make pictures under actinics.
well, i was messing around today and i took what was supposed to be a nice shot, but ... the white balance i had set in a different section ofthe tank, didn't work quite as good on the bottom. so the picture turned out a bit underexposed, and too purple.
but no worries, nothing that a little photo editing can't fix.
use your favorite photo manipulation software, and find the option where you can change the color levels.
then say "auto"
it is usually pretty good at guessing the correct values, unless the shot is really messed up, and you have to setthem manually.
this is how mine turned out;
i split it with a before-and-after in one image.
