What format are you shooting in, and can you download GIMP and UFRaw onto your computer? If you're shooting in RAW format, I can work the red outta those using UFRaw in GIMP. It takes some playing with levels, but another great tweak is to learn how to use the white balance dropper thingy.
Actually, thinking about it, I could probably get better color even if it's just a jpg or png format.
Those cats ain't gonna help you out, unless maybe you get them totally baked. Was there an opportunity for that?
Btw, I keep forgetting, you're in Pascal Baudar territory! He does wild foraging, fermenting, all KINDS of stuff to do with wild foods and he's down in the LA area. I've wanted to go on a walkabout with him, do one of his classes, something, but I can't really. Hold on, lemme link you his new book. His photos, which he does all himself, are seriously amazing, too.

Ok, back to weed and photos. You can change the exposure setting, but know that the lighter areas will end up "blown out" and it's actually easier to retrieve information from an underexposed shot than from an overexposed shot.
