Monochromatic Triptychs (last attempted in 2005). The third graders made amazing monochromatic paintings this year so I thought it would be fun to use our iPads to turn them into triptychs where they could see their original image and two others with color filters in a different hue side by side.
I played with two free apps to make my examples happen:
Crazy Color Booth for the filters
Pict Collage for the triptych
I'm sure there are other apps to do this, but we have these installed and ready to go, so why not use them!
