I think you could probably write an entire book on the subject and power of curves adjustment layers within Photoshop. Curves could be the perfect editing tool, whether you are a wedding, architecture, or even forensic photographer. In the video, I examine some of the ways I use curves on a daily basis for my interiors and real estate photography work. I also attempt to explain, by way of an example, how powerful an editing tool curves can be.
Below are before (left) and after (right) images where I have used the white point adjustment technique discussed in the video. This is a way to really liven and brighten up interiors by essentially utilizing the entire dynamic range available to you for the interior only. Click and toggle in a slideshow to see the effect this technique has on the image.
