So I found an old picture of my dad skiing at Lake Martin.  I drew a quick Pen & Ink sketch of it, then scanned it in.  Took the drawing into Photoshop to fine tune it and color it.  I used Levels to darken the ink because the scan mutes the black a little. (Drag middle slider to right).  Then added a new layer on top and Image > apply image to stamp all on that layer.  Select > Color Range to pick the blackest black.  Set fuzziness high.  Then cut and paste this selection onto a new layer so that you can color underneath the black.  Then turn on the soundtrack to Les Miserables, and boom, a couple hours layer you have a colored drawing! (Didn't quite stay true to likeness.)

Shortcut keys make life so much better.  Learned a few new ones today:

With the shape drawn using the lasso tool, hit B and ALT-click the color you want from your reference.  Then hit SHFT +F5 to fill the selection with the color that you chose.  Then L gets you back to the lasso tool.  This is in Photoshop.
