Carmen is making a powerpoint slide show to present pictures from her recent trip around the california bay area. for a group of photos from her visit to a mining town that commemorates the california gold rush, carmen would like to make these color photos look old, as if they were taken with a camera in 1850. she has in mind an aged look, but she does not want the quality of the picture to suffer.

in the picture tools format tab, carmen would most likely find an option that would accomplish this by selecting

crop.
change.
color.
corrections.
