Case G-2Flippy and Hammy, two local party clowns, have been taking lots of digital photos during their recent gigs. They want to use the photos for promotion, both by posting them to their Web site and by creating some eye-catching ads and hand-outs. Most of their pictures have been taken against a solid black background. While he sharpens the photos, Flippy is extremely happy that they use a solid black curtain as a backdrop at their shows. Why?
A. The black background makes for much stronger edges, as edges are the points in an image where pixels that are close in color abut one another. B. It is much easier for him to use the Lasso tools to select portions of the image. C. With the black contrasts against the colors of their costumes, the edges are already very sharp. D. The black background can easily be replaced with colors that are more printer-friendly.
