This is an interesting subject. I had a go at deveopling some 16mm B&W reversal at home recently (out dated 7278 given 1/3 stop more exposure). Although the film density was a bit thin, (I'm assuming this as the sprocket area was not black, but more of a darkish grey) the image was great and encouraging. I'm up for some more experimentation in this area. (time consuming as it may be)
Reading above about the possible low contrast when processing B&W neg as reversal, will pushing the film a couple of stops increase the contrast? would it be better to push 7231 rather than the faster 7222 stock ? or am I really asking too much of the film here?
I'm an experimenter, and so not concerned about the inevitable golf ball sized grains in the emulsion as a result of this.
