A simple way to match color tones in Photoshop

Matching colors in Photoshop can be tough and time-consuming. However, there is a way to vastly speed up the process as we can see in the video below by Antti Karppinen. Although the technique in the video below is aimed at dealing with issues that arise during compositing, it can also be used for balancing colors when using multiple light sources. For example, if you are using artificial light outdoors, you can use this Karppinen's method to match the colors of artificial and natural light sources provided that you make selections within your image.
The technique involves creating a blank layer and filling it with 50% gray. You then change the layer blend mode to "luminosity," which will give you a dull color image. To help make it easier to see the underlying image, create a Hue/Saturation adjustment layer and max it out. The next steps involve tweaking the individual color sliders on the layers you want to match, which you can see in action in the video.
