Quickie Tech Note...

Auto White Balance sucks.

A quick hack to overcome some of the bizarre colors rendered by auto white balance in, say, football photos shot at night in available light under metal-halide field lighting is to select a known white area, copy and paste it into a white_sample.tif, and save that.

Then paste the white_sample.tif into a photo that needs a little help, drag it up to a corner, and flatten layers.

Do an Enhance > Adjust Color > Color Cast (or whatever your specific syntax, you get the idea) on the pasted white sample, and voila!

Quick-and-dirty, and it does an amazingly good job most of the time.
