Blend If
With Blend If you let a layer blend only based on the brightness of that layer or the layers below it. Two slider bars decide which tones do and do not take part. It is a fast, non-destructive way to blend only the shadows or highlights, for example.
Double-click a layer to open the layer styles and use the This Layer and Underlying Layer sliders at the bottom. Drag a slider inward to exclude dark or light tones, and hold Alt to split the slider for soft transitions. Ideal for showing a texture only in the highlights or keeping a color layer out of the shadows. Tip: this often saves a lot of masking work, try Blend If first.
