In a recent post, I mentioned that the Color Contrast feature gets overlooked. On the other hand, I think the Mix Channels function gets misunderstood. Many editors have this feature. It can be very useful but the usefulness of it sometimes gets overlooked. I have a video tutorial on it here:
And here (Part II, which is shorter but has some advanced examples)
Here is an example I came up with that I think shows how useful mixing channels can be. First, here is the original image:
After using the mix channels, here is the result:
As you can see, this image is quite different! The image was Auto Balanced to brighten it a little. Then, after the Mix Channels was used, the Undo Brush was then used to only put back the skin. As I’ve mentioned before, to really get spectacular images, it’s important to use multiple functions, and the Undo Brush is a must in order to really bring out some areas and subdue others. But, the real star in this instance is the Mix Channels, helped along with the Undo Brush to isolate only the areas we wanted to keep (the hair, lipstick, and paint).
