Screen

Screen, the second of the Lighten group of blend modes, is often likened to projecting multiple transparencies onto the same screen. As Screen's neutral color is black, this blending mode will leave black unchanged. Dark colors marginally brighten the picture, but as the blend color lightens, the image becomes increasingly lighter. This can make certain images look bleached or overexposed.

Self-blends and changing the opacity

A self-blend simply lightens the image, especially in brighter areas, resulting in an image that appears overexposed Experiment with the Blend If slider in the layer's Blending Options—you can restore contrast or limit the blend mode's effect to the shadows or to the midtones and highlights

Blending with an inverted self-blend produces a partially reversed effect where formerly dark tones are now washed out, while mid- and lighter tones are brightened—the overall effect is curious

Here, the Blend If slider has restored the shadows.

An interesting use of the Screen mode is to apply it to a lens flare Fill a new layer with black and change its blend mode to Screen, then apply the lens flare Screen renders the black invisible, and adjusting the black layer's opacity allows you to fine-tune the flare's strength Of course, you could do the same if you had applied the flare to a copy of the image layer But this technique is really useful if you later decide to move the flare—all you need to do is move the black layer Just watch out for borders if you add so much flare that it overlaps the image edge—the way around this is to temporarily increase the canvas size
