Thanks for all your input thus far, folks - very much appreciated, as always
I'd love to try stand development, but given the feedback and the nagging doubt in my mind that I'm trying to run before I've even figured out walking, I'm going to stick to regular development for now and aim to get the best from my negatives with that approach (per the links @Viking42 provided - thanks, Svend
).
When I get round to shooting the HP5+ I have in the freezer (which may not be for some time), I might use that as an opportunity to try semi-stand development with my existing Rodinal, rather than using a different developer more suited to that film for regular development. Since my original post, I've read that HP5+ and Rodinal play well (or at least "better") when using semi-stand development, and the low-bromide chemistry - especially at 1+100 dilution - is such that so-called "bromide drag" is, apparently, unlikely. Plus, I
think I prefer the idea of trying different development methods with the same developer over the same method with different developers.
Thanks again for the feedback, folks
