I've used a changing bag for years. Haven't noticed any problems -though I contact print mostly. I used to take my 4x5 on camping trips. Load and reload film in the bag on a picnic table etc.
I didn't want to limit the shots I took on a trip to the number of darkslides I have. Can't imagine doing handling roll film in a bag. I've reloaded an 8X10 pinhole camera in a changing bag - thats difficult Gord --------------------------------------------------------- Gordon J.
