If you’re looking to reverse grayscale in Photoshop, there are a few things you’ll need. First, you’ll need a color palette. Second, you’ll need some gray levels. Finally, you’ll need to set up your layers and masks. Here’s how:

  1. In the Layers palette, select the gray level layer and click the Edit button.
  2. In the Layer Properties dialog box, set the following properties: a) The layer’s name should be Grayscale (or whatever your desired name). b) The layer’s opacity should be 100%. c) The layer’s size should be 1/8th of an inch square (or whatever your desired size). d) The layer’s position should be at the bottom of the image window.
  3. Click OK to close the Layer Properties dialog box and return to Photoshop’s main image window.
  4. To reverse grayscale in Photoshop, select one of your color layers and click on its Edit button; then set the following properties: a) The layer’s name should be reversed (Grayscale on top). c) The opacity should be 0%. d) The position should be at the bottom of the image window (the same spot as before).
