I want to share with you a really clever new way of correcting images - it was discovered by Jacob Rus and is appropriately called Jacob's Ladder. When Jacob posted this technique, even the great Dan Margulis was speechless. It is so simple to do and yet extremely powerful on awkward images.
It is probably easier to experiment with this technique (I've included some Photoshop Actions you can download) rather than try and understand the nuts and bolts of it - but let me attempt to show you...
Well, that is hardly impressive, but hopefully you get the idea. Adjusting colour is simply a matter of making a colour warmer (magenta or yellow) or cooler (green or blue) - independently of it's brightness - wait until you try it on real image.
There is a wee annoyance (using Photoshop's curves dialog) and that is having to add extra points where you do not want any change, and also the Info Palette doesn't work (one of Photoshop's bug/features!) - but using a Colour Watcher gets you around that problem.
If this exciting new idea interests you, then read on...
