The friend is a photography teacher at a high school. Recently the teacher that taught digital art was involuntary transfered to another school and replaced by, in her words, an "inadequate" teacher. She said the new teacher only teaches how to apply photoshop filters.
I don't have much more information than that, but she enlisted me to help her come up with some information to why this is not an effective way of teaching digital art. Her exact quote was, "why photoshop filters suck."
