I have adobe Photoshop Elements 9 that I purchased last year. I was watching a tutorial on how to darken hair color. However, my smartbrush doesn't seem to be working correctly. When I click on the smartbrush icon instead of a circle type marker does not appear, only a + like marker appears and all it does is mark streak marks on the part of the hair that I want to darken. My question is WHY doesn't my smartbrush marker appear as a larger circle marker as it does in the tutorials? Why isn't my smartbrush tool working correctly?
