Yep, a very good technique for quick stuff.

With the Hip Replacements equirect I wasn't unhappy with the original 
look, but I thought I'd experiment a little - and this really did 
help, once I knocked it back from its 100% impact. And masked it off 
completely in the nadir area, as that was greening up the floor 
noticably more than it really was.


>What did you mean by cross-process curves?

Cross-processing is a technique from the world of color film 
developing, where one kind of film stock is processed using chemicals 
meant for a different stock, producing a certain general kind of 
color and contrast alteration. As usual, Wikipedia is a reasonable 
starting point for info:
http://en.wikipedia.org/wiki/Cross_processing

This article:
http://www.photoshopsupport.com/tutorials/or/cross-processing.html
shows how to do this manually in Photoshop in the Curves dialog. But 
Photoshop CS3 (and CS4) also has a selection of ready-made curves 
settings that can be chosen without fiddling - making them both easy 
and repeatable. (As would be saving a custom set of curves as your 
own preset, but this is done for you already.)

Here's a screengrab of the thing in use:

Note, though, that this preset merely simulates one of the many 
different results that true cross-processing, with different films 
and chemicals, can produce. Here's another tutorial that looks at 
different manual curves settings:
http://www.layersmagazine.com/curvy-cross-processing.html

Have a go! If your version of Photoshop doesn't include the Cross 
Process preset then just tweak the RGB curves individually so they 
look similar to the lines in that screengrab or in any online 
tutorial. Accurate matching of those lines isn't as important as the 
effect you see, so play with it.
