STEP-BY-STEP: PROCESSING FILES:

  • Open Photoshop
  • Make sure it is set to "essentials" in the upper right hand corner drop-down
  • Find and open your first file
  • Notice on the right hand panel there is a tab labeld "Background." That area will list all your files and changes to your files. However, we DO NOT want our first image to come in as the background. So... do a right mouse on that and select "Duplicate Layer" and change the name of that new duplicate layer to "LAYER 01"
  • Now go back to the background layer, do another right mouse and delete the background layer.
  • Be sure and change the layer from Normal to Screen
  • From the "Image" menu option change the Mode to RGB
    • To colorize the image select the following:
      • From the "Image" menu select "Adjustments"
      • From "Adjustments" menu select Hue/Saturation
      • From inside the Hue/Saturation Options
        • make sure the "colorize" box is checked
        • change the color to your desired color as follows:
          • 0 is red, 60 is yellow, 120 is green, 108 is cyan, 240 is blue, 300 is magenta and other blends are as you select
        • change saturation to 100
        • change lightness to -50
  • Make sure you can colorize the image. If the colorizing options are grayed out, you may need to "Rasterize" the picture. Go to the "Layers" menu option and select "rasterize" (you may need to make your layer a "smart object" first.
  • Select FILE and SAVE to make sure you preserve the new file

► LAYERS

This is KEY. Click on FILE and choose PLACE:

Open the second file and place it right on top of the first and click the mouse to "place" that image once it is centered.

Notice there is a new layer there on Photoshop on the right side panel..be sure and label that appropriately

Now repeat that process with each picture

Make SURE the color pallet toolbox is available:
