Exposure layers are a great way to add light and shadow to your photos. They can be used to add highlights and shadows, or to create a more realistic photo. Here are some tips on how to use exposure layers in Photoshop:

  1. Choose the layer you want to use as your base layer. This will be the layer that will contain all of your photo’s data.
  2. Drag the opacity of the base layer down until it is at about 50%. This will make your photo look darker and more realistic.
  3. Drag the opacity of any other layers in your photo up until they have an opacity of about 75%. This will make them lighten up and give your photo a more natural look.
  4. To add light or shadow, drag one of the layers above the base layer down into the darkness or lightness range that you want it in. For example, if you want your shadows to be darker, drag one of the shadows down into the black or white range. If you want your highlights to be brighter, drag one of the highlights down into either yellow or blue range (depending on what color you want).
