Light Depth with Layer Blending
Studio lighting can be quickly and easily dramatized by blending multiple layers. Duplicate a layer with a subject by pressing Command – J (PC: Ctrl-J). Desaturate the new layer, then adjust the Levels dialog (Command – L [PC: Ctrl-L]) to create a strong contrast. Now, apply a Gaussian Blur (Filter>Blur>Gaussian Blur) to the new layer and set its blend mode to Overlay, which amplifies the saturation of the base colors, while retaining the tonal contrast of the new layer. This effect can provide a strikingly more provocative sense of depth with very little effort.
