GIMP Activity 6a

Picture
This activity is not an official teaching activity, but I've provided some starter videos to help students get going.

Remember to try different options under the Color dropdown, especially "Color Balance" and "Hue/Saturation".
Warning!!!
If you use the strategies below, then the "Multiply" layers may not behave as you expect.  Be sure to read the my comments below beside video #4, then watch video #4.  Please ask for help if you are still confused.

Updated Video Instructions

The first video series (below) did not prove as straightforward as I had hoped.  So, here's a simplified version.
Video #1
  • Create a new layer ("Skin Tone")
  • Go back to the baby layer (so highlighted)
  • Lasso select the baby
    (finish back where you started)
  • Change to the new "Skin Tone" layer
  • Bucket-fill the selection onto the
    "Skin Tone" layer



Remember these Keyboard Shortcuts:
  • Ctrl-Z  = "Undo"
  • Ctrl-Y  = "Redo" (gets back the "Undo")

  • "+"     = Zoom In
  • "-"      = Zoom Out
Open video in new tab or popup window.
Video #2
  • Set color layers to "Color" mode
    (top of the right-side "Layers" tab)
Open video in new tab or popup window.
Video #3

Original Video Instructions

When I first made videos for Activity 6a (see below), I thought they were simple and straightforward.  I've since learned otherwise.  That's why the updated videos above were made.  However, should you wish to try out the old videos, here they are!
  • Selecting, copying and pasting to create a new layer.



Remember these Keyboard Shortcuts:
  • Ctrl-Z  = "Undo"
  • Ctrl-Y  = "Redo what you just Undid"

  • "+"     = Zoom In
  • "-"      = Zoom Out
Open video in new tab or popup window.
  • Fail at the start, but then succeed later!
Open video in new tab or popup window.
  • Setting layers to "Multiply" and "Color"
Open video in new tab or popup window.
Putting "Multiply" layers back together.


WARNING!!!
When using "Multiply" layers:
  • Remember from Math class that:
    0 x 1 = 0
    0 x 2 = 0
    0 x 3 = 0
    0 x <any number> = 0 !!!!

  • So, if using a "Multiply" layer, the transparent checkerboard background means the color = 0.

  • This means that in your final version, you must "Merge Down" all your background layers together.
Open video in new tab or popup window.
  • Save as activity-6a.xcf
    -     Be sure to upload this as a "File" on your Weebly site

  • Export as PNG or JPG - activity-6a.png or activity-6a.jpg
         
    - Be sure to upload this as a "Picture" on your Weebly site
       and click the first button to "Open larger image ..."
