Digital BW, The Print

Don't know if this is germane to the topic, but I do traditional b/w
photography and have switched from PhotoFlo to LFN for my film
development. PhotoFlo, if mixed and left to stand, gets "skanky", stuff
begins to grow in it. I was careful in using it, but sometimes I got
scum on my negatives. Since using LFN I've had none of these problems.
