A Look at One of Photoshop's Most Powerful and Least Used Features

Photoshop is an extremely nuanced and complex program, which means there are often several ways to accomplish what you need to do. One of the application's most useful features, Blend If, is a bit hidden behind those multiple layers of menus, but it is one well worth knowing, as it gives you powerful and versatile capabilities for a range of editing scenarios. This excellent video tutorial will show you the ins and outs of Blend if and demonstrates how it works through a series of double exposure edits. 

Coming to you from Blake Rudis with f64 Academy, this great video tutorial will show you how Blend If works in Photoshop and how to use it for combining layers. The Blend If function works by combining one layer with another based on the grayscale luminosity or the luminosity of one of the color channels should you so choose. This allows you to quickly combine layers into a double exposure or to add a bit of vibrancy to a sunset, but more importantly, it allows you to do it very precisely without needing to hand-draw complicated selections for masking. And the best part is that it allows you to feather the adjustment, making it easy to create a subtle transition that makes the overall edit more believable. Check out the video above for the full rundown from Rudis.
