After this tutorial, you will be able to turn this: Into this:As Cyn mentioned in her primary colorizing tutorial, the key to a good result is in a good clean source image. The cleaner and better resolution the original source, the easier it will be to work with and the better it will end up. Take particular care to avoid images with large blown out white sections, as these will never look right in the final image. The original I used above was around 2000 x 2000 pixels.The nice thing about this method is the nature of adjustment layers themselves, you can always go back and change them, messing around with the colors as much as you want until it finally looks right. It also incorporates the layer mask right into the adjustment layer, so you can clean up your selection edges as you go along. It also doesn't require any pre-selection of colors as in Steveo's tutorial, or blending of colors into one another as in Cyn's (though both are excellent methods).Don't forget to save early and often.
