I don't understand the term "bromide drag", but I'm wondering if this is an example...
There are white streaks appearing to emanate from the top of the church tower (that's St Mary Magdalen's I think, Taunton). This is Tri-X, devved (with Ilfosol 3) in a Rondinax, so the film is moving longitudinally (vertically in this image) semi-continuously. (I don't wind all the time, but do two partial winds, wait two seconds, repeat... no idea why but it usually seems to work.)
I used to think that the streaks were the result of depleted chemicals, but it's a negative, so the tower (under-exposed) has received less light, and so the chemicals should be less depleted there, rather than more. Can anyone explain for the simple-minded, please? (Oh, I can usually understand a technical explanation, perhaps with a few questions...)
Thanks!
