Read the manual? That's no fun! Seriously, will try again with your recommendations....how do you agitate?
I agitate by saying things, under my breath, that the film doesnīt want to hear. On the other hand, perhaps itīs only myself that I manage to agitate, which would serve me right.
Why not use a less "artsy" developer and do things in the normal manner? The only people I have heard recommend it (Rodinal) seem to belong to the more intellectually inclined photographic world. Having wasted much time in my youth with all manner of proprietary soups, I eventually took the plunge and devoted the rest of my black and white life to D76 1+1 with 35mm HP3(4) and 35mm FP3(4) and 120 TXP. Was nice to find something that worked every time and remained dependable. Much like Kodachrome, then, except that I didnīt have to think about developing that, just about getting it developed. Or processed, if you prefer.
Anyway, navel gazing aside, how did you manage with it? I ask, as this post is somewhat late in seeing light of day and you will probably have done what you wanted to do.
