I'm a noob but I realize how much film costs already.
I priced a 100' roll of Illford HP5 at B&H; it's $55.00
If I get 20 rolls out of that that comes out to $2.75 a roll...not bad at all.
Even with buying the film cassettes and bulk loader it's cheaper than buying Tri-X.
Do you more experienced folks see any flaw in my plan?
