I've developed a new method, called parameter free color correction, for correcting color shifted prints. It in principle has no parameters, and corrects the color with the push of a button. The only variable is a slight contrast adjustment if it is desired, but it works without contrast enhancement. It's also extremely fast. It's done in less than a second. Here are some results for Team Negative1's reel 1 preview:

Just to make this clear. These colors were reconstructed, without any prior knowledge of what the colors should be.
