As I recall you published an article on this bleach-redevelop procedure a few years back in one of the national magazines, Darkroom Techniques perhaps. Is that article available online? If not, wonder if you might post here some of the details, such as bleach formula, bleaching time, etc. here. This procedure has the potential to be very useful with low contrast films such as BPF when they must be used in low contrast situations.
