Ilford film users....why is Ilford film so difficult to roll?greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread
I usually use Kodak brand films but have, on occasion, used Ilford Universal 400 and Ilford's SFX 200 film. When I go to roll the film onto the reel, it seems to stick in a certain spot each time. My reels aren't exactly new; however, I've had no problems with Kodak films whatsoever. Usually I just cut the film off at the point where it sticks and reload the second piece onto a separate reel. It always comes out okay and doesn't stick anymore after that. Has anyone else had this problem? If you have any advice for me, I'd greatly appreciate it.
Thanx in advance.

i've noticed similar problems with ilford films. it's always seemed to me that the film base is a tad thinner on ilford than on kodak, so the film is therefore more flexible. this extra flexibility--i.e, lack of stiffness--makes it double up on the reels more easily that kodak films, with their stiffer base. i've heard some photographers use this as an argument that ilford films deliver higher contrast in the enlarger: if the base is thinner, there's less diffusion of light passing through. i personally can't tell any difference.

Thinner film base, I think.
