PHOTOSHOP: Gradient map + Luminosity = Great way to add dimension to photos

So I was experimenting with colorful designs, and one great way to do this is with the gradient map feature. I usually create different parts with the gradient map, and overlay them on top of each other in a layer of blended colors, to get an amazingly bright and colorful look without a boring looking, banded gradation that merely tints the photo. Well, as I was doing that I discovered that the luminosity overlay is a great way to add depth to a photo by using it in conjunction with the gradient map. This allows you to add deep colors into the photo, rather than working with what's only in the image. Above is the original photo, untouched by photoshop. Great composition, beautiful model, but really quite unspectacular. But by adding a gradient map you get a semi-psychadelic image like this:



Pretty cool in it's own right, but this is what we'll use to work with on our luminosity. You'll have to play around with the points on the gradient map to get a desired look, but it's well worth the results.

Once you have your desired gradient-map-ified photo, paste it above the original, and change it's layer properties to luminosity. Voila! That is all you really need to do for some quick enhancements, though you might take it a step further with levels, hues, curves, etc...
Here is the image after said adjustment:





Have fun, hope this was useful!
