1. Apply a Gaussian blur to a duplicated layer set to Overlay blending mode to softly boost contrast. A Vivid Light blend gives a more dramatic effect.
2. Use selection tools to isolate a subject on its own layer, then apply filters like Dark Strokes to the background layer to add effects behind the subject.
3. Add color and drama by duplicating the layer and applying a Neon Glow filter in a complementary color at a low glow size and brightness. Set the blend mode to Overlay or Vivid Light.
4. Easily soften portraits by duplicating the layer and applying a low-opacity Gaussian blur. Adjust opacity until it looks dreamy.
