Are these guys still around ?.....I remember seeing these ads from NYIOP in publications like Modern Photography and Popular Photography waaaaaayyy back in the 70s and 80s. While I do not know much about these guys other than what I have seen in their ads (which is not very impressive), I would suggest that if you are really interested in learning the nuts and bolts of photography, then a correspondence course is NOT the way to go. In other words find some time in your busy schedule to take some non-credit courses at a local community college. Interacting with your fellow classmates and instructors, is something that no correspondence school can ever touch and I am willing to wager that it will be a whole lot cheaper.
