One of the masks used in today’s image started out as a selection based on “Color Range” (Select/Color Range). The white walls of the building had a distinct blue cast to them. Selecting the colors that make up the white walls and using the Fuzziness slider picked up more of the wall components. It also selected a few non-wall areas. Eliminating the stray picks was an easy matter of using the Lasso (L) Tool while holding down the ALT key to remove parts of the selection. As is usual here at the gallery, the selection was right clicked on and Save Selection was chosen. The reason for saving the selection as an Alpha Channel is to have it available for use on latter Layers. You can have many Alpha Channels, so why not keep anything you select “just in case”. Once the selection was made it was applied to a Hue/Saturation Adjustment Layer. The Saturation was lower to remove the blue cast from the walls.
The Content Aware Fill in CS5 makes easy work of removing most of the flowers and stains on the wall. The heavily textured nature of today’s image plays right into CAF’s hands. It’s going to look for nearby patterns and make a judgment from what it finds. The more texture in the general area of what you’re trying to fill the better it works. Was it perfect? No, but it was darn close.
