I am a little confused about whether it contains Sulfite or not. According to Tom the latest version doesn't, so should produce image staining and tanning. Those using the latest version can perhaps shed light on this. Is there any staining or tanning effect?
What's its active life like compared to Rodinal? Much shorter and more like other PQ developers would be my assumption but that's all it is - an assumption.
Andy. I note you use it for HP5+ as do some other posters with good results. How does it compare with ID11 or DDX for 35mm HP5+ for instance?
I'd assume bigger grain than, say, Perceptol but again it's an assumption. At what size print might this bigger grain, if it is bigger, show itself compared to Perceptol?
