Have you ever looked at a picture and wondered how the toning was achieved? How a special mood was created through controlled shifting of colors? Ever wanted to recreate those colors in Photoshop?
Some will love us, some hate us for it, but with GradientGrabber you can quench your thirst for gradients! Head over the your favorite photoblog and steal 'em all!
Apart from extracting gradients from toned images you can use this tool to create new grading curves from regular color images. The results are impressive, so try it now!

As for the picture, this is an experiment grading the same image with different curves. The woman, which is called Mary Bloody, is part of a bar advertisement. Of course we couldn't resist the 50's style of it. How's that for a product launch, heh? With girls like her you could sell anything ;-)
