So it does seem that I was wrong in a previous post about the use of photo flo as I was still getting streaky negs but I seem to have sorted it now….
I have found that my favoured way is to make up a jug of Photo Flo, not accurately – about 300ml of water and about half a ml of Flo (use a syringe) and then ‘drag’ my negs through it. I attach the regular drying/hanging weighted hooks to both ends as normal for drying and then whilst holding them both in each hand, allow the film to curl slightly into a C shape under its own weight. I then lower it into the jug and allow the length to submerge in the jug. You can then do this a few time, hold it up and you will see the solution running off. A couple of dips normally does the job just fine. The strips of film are then hung as normal with a towel under them to catch the remaining solution as it rolls off. Again, don’t wash the solution off, and now I don’t even recommend squeegeeing them – there doesn’t appear to be the need and you eliminate the risk of damage to the negs.
Hope that helps somebody…!
