Overview

I created a couple of composite images (artifacts) to demonstrate that the code from my Image Scissors project works. The artifacts are not very complex. I followed the same procedure for each of the artifacts:

• Find a background image
• Find an image with an interesting foreground item
• Open the foreground image in the Image Scissors application
• Trace the foreground object
• Save the mask of that foreground object in a tga file
• Open a background image in Photoshop
• Open the foreground image in Photoshop
• Select all of the foreground image and copy
• Paste as a new layer into the background image
• Add a Photoshop layer mask to this newly created layer
• Open the foreground object mask tga file, Select all, copy
• In the background document activate the channel that is the layer mask
• Paste the object mask into this layer mask channel
• Scale this clipped foreground object and move it to the correct location
• Smooth out the edges of the layer mask channel

Boarding Yosemite

	The Foreground Object: Darcy boarding in the forest near Leavenworth, WA
	The mask created by the Image Scissors application
	The Background Image: A picture from the top of Royal Arches rock climb in Yosemite
	The Composite Image: Snowboarding the cliffs of Yosemite. Darcy is illuminated differently than the background, so this composite is only marginally effective.

Diving Limestone

	The Foreground Object: Darcy scuba diving in Puget Sound
	The mask created by the Image Scissors application
	The Background Image: A picture of limestone formations on Mt Civetta in Northern Italy
	The Composite Image: Diving in Limestone The illumination works better in this composite. The natural edges in the rocks hide the discontinuity with the imported image.
