Yesterday i was trying to load a 35mm roll on a plastic reel in light, it was not easy [i am sure it a Patterson reel], and when i tried to do it in a changing bag, i think i will never load it on the reel, either the changing bag was not pumped and all the time coming around my hand and i have to move for space, not easy for 35mm then what i will do with a 120? i was practicing on my friend film kit before i buy mine, he has a plastic tank, but i never saw him developing as he tried once and failed and then he decided to develop in the lab always, so i will practice on his developed ruined film with reel until i can do it properly in dark, but in all cases, i want to order and do myself at home everyday, i don't go there to the photography club to use his kit.
