The WT challenge is to use reinkers to make a background. Lucky for the CCEE team that for this week's CCEE Challenge, Lynn is featuring a background technique known as bokeh. The word bokeh is a photography term which describes the way a camera lens creates out-of-focus points of light.
There is an excellent SCS tutorial which explains the steps taken to create this unique look. Take a peek at it if you are not familiar with this background technique.
