Part 1, Activity (40%):
You may download an acrobat or word processing document to help you with this.

 • Create a lab8 folder
 • Copy any image(s) you wish to use into the lab8 folder

   • Open an image and edit as needed, such as
         • adding additional images or portions of images on separate layers (BE CREATIVE)
         • cutting or cropping as needed
         • adjusting brightness and/or contrast as needed
         • using the dodge, burn, cloning, pencil, paintbrush, or ink tools as needed (may place on separate layer)
   • Create a new layer for the image
   • Use the selection tool to draw a rectangle, then use edit/stroke to outline the rectangle on the new layer
   • Use the 'fill with color tool' to flood the rectangle with color
   • Add your name using the text tool, place the text over the colored rectangle
         • rearrange the layers as needed (drag a layer up or down to impact what is visible)
   • Save the image and it's layers in the xcf format, calling it lab8.xcf (or .psd if using Photoshop)
   • Save and Export a flattened, merged version of the image to the png or jpeg format, calling it lab8.png or lab8.jpg

Please don't simply combine random objects...
... actually use to tools to enhance an image or images.
You get to choose how you use the tools, but this should not be a two minute lab!

 • Zip the lab8 folder, rename it to yourname-lab8.zip and submit in the D2L Lab 8 dropbox
