In my photography class at my high school they recommend we use Ilford HP5 plus from a local vendor called The Camera Company. I stopped in yesterday to pick up a few more rolls, but the man at the counter told me they were all out of the usual kind. He offered me the more expensive Ilford HP5 plus delta professional for the same price and with my student discount, so it was a total steel. I showed it to my teacher today and she was unfamiliar with it. I checked the Ilford website to see the pros of the higher end film but it has relatively the same description as the normal one. So I was just curious and please excuse my ignorance, what makes it better? Will my prints come out better quality?
