Photopea Day 3

Introduction:

  • Questions since last time?
  • In what situations would you want to combine images?

Masks

Using Masks to “cut out”

  • Do the Mask Exercise file here
  • Then show them they can apply that same concept using two images

Combine 2 similar images

  • Log Road Block images
  • Auto-align layers
  • Create a mask
  • Paint on the mask to bring second person in

Select and Mask Workspace

  • Select>Select and Mask
  • This window will allow you to make more precise selections for masks
  • Change view mode to the one you want (marching ants, onion skin, black & white, etc.)
  • There are familiar selection tools here, but there’s a new one: refine edge brush tool
    • Use this tool to make finer selections. This tool works really well with selecting hair/fur.
    • Demonstrate by using a picture of someone with long hair (Red-Haired Girl.png)
    • Quickly select the person, then refine the edges using the tool
  • You can also make a feathered selection by upping the feather under “global refinements”
    • A feathered selection will “fade in” instead of having a hard border
  • Click “OK” when you are finished. You will see that a mask has been made from your selection.

The Select and Mask workspace does not exist in Photopea, but there’s a similar feature called “Magic Cut”

  • Select>Magic Cut
  • Paint green on the foreground of the image (the part you want to keep) and paint red on the background (the part you’re getting rid of)
  • Paint gray to erase
  • If you practice on the Red Haired Girl file or some other picture with hair/fur, Photopea does a decent job of masking around the hair, but it probably won’t be perfect.

Photopea also offers a “Refine Edge” tool, but I’ve found it doesn’t work very well. But you can try it if you’re feeling brave.

Application: Use everything we’ve learned so far to Photoshop Garrett’s face onto Daniel Burbank’s (astronaut) face

  • Make sure Daniel Burbank and Garrett are on two separate layers
  • Use lasso tool to select Garrett’s face (just the face, not the head/hair)
  • Select and Mask Garrett’s face/magic cut
  • Feather 
  • Re-size Garrett (cmd+T) transform shortcut is option+command/cntrl+T so he’s aligned with Daniel
    • Adjust the opacity of Garrett to do this easier
  • Clipping masks with adjustment layers (to get Garrett’s face to look less corpse-like)
  • Apply a color balance adjustment layer and increase yellow and red
  • Use a clipping mask so it only applies to Garrett’s layer
