I looked at the demo of this, (as a photoshop plug in) didn't really see any improvment over the filters that already come with PS. Maybe I'm missing something.
Basically, I need the batching for the times I shoot a load of images using the wrong color settings on the camera or other stupid stuff. I'm no pro and 90% of the action we shoot is off the cuff no studio lighting etc. so being able to batch the images with color matching etc really helps. (I finally figured out not to use auto white balance on the d100 this saves me a bunch of time since all the images at least have the same look)
4 years into this and still bang my head and go DOH! at least once a week LOL!
