i've never been able to find much on it..except for what i've done. i found a couple of people who discussed it and that was about it.......art therapy isn't exactly like it....different mediums and applications.....phototheraphy involves a lot more talking than art therapy. less interpetation of results by counselor alone, more direct with patient. i use "costumes"....very telling.....i also took my dog, tippy, to group and he was very good with the patients. there are probably a lot of portraits of a patient and tippy floating around Oklahoma......:-) i don't know what the parent company did with it because they merged with another big company and i lost contact with corporate. just stayed in contact with the Pdoc that i worked under......
