But, your questions are always about going in completely blind... You want other peoples experiences, when the variables (how you meter/how you agitate/ what your water is like) negate any value to the information. YOU NEED TO DO THE WORK YOURSELF! Even if you're spoon fed what works for others, it probably won't work for you. For all of the times you've rejected the one film/one developer advice, it's really the only way to begin to understand the science of photography. It's only after you've worked within that limit that you'll be able to transfer that knowledge to other film/developer combinations. Until you decide to get serious, and do the work, your images will suffer. Do the work now.
I guess I just don't think people meter that wildly different that in terms of exposure it will be that horribly different. There's this consensus with people that if you shoot D3200 at 3200, you should develop for 6400 ... it's pretty much repeated by everyone ... no matter how they meter, that's what everyone says... so... it should be relatively the same with HP5+ when pushed ... if I got one or two people's consensus on things, that would be helpful.
I can't standardize on only one film, it's impossible, because I shoot on many different formats, and the films I enjoy using aren't available on all formats... if I'm shooting models, I like PanF+ but that's not available in 4x5.... if I'm shooting models but I want to use outside light as a balance, and have a great depth of field, I need to use something like TMY-2 @800 in order to balance the inside light and strobes and get a good depth of field, so that too I can't use JUST one film ... if I'm shooting all inside with no lighting, I need D3200 or P3200 (may it rest peacefully) so again I can't just use one film... and in this case, Rodinal won't do it, so I have to also use a different Dev (DD-X) ... if I'm shooting 4x5 inside with no strobes and the lighting is so low I need something that hits 3200 I will need HP5+ because that's all that's available in sheet film.... again different film, different dev...
So, yes I can do the work... but saying you should stick to one film, one dev... although repeated often, doesn't make ANY sense to me... in any way, and I think it's just ludicrous ... either that, or they specialize in one thing only, and so don't have this constant change in atmosphere to deal with, and so they don't understand or refuse to see it... but not everyone ONLY wants to shoot still life's in a studio...with one film, and one developer, for 20 years...
I'm not at all mad at you Eddie, I just wanted to elaborate...
Also, in this case, HP5+ is also the ONLY film available in 127(46mm special run thanks to Ilford's ULF special order) so it's relatively new to me, I've only shot it a few times in 120, and then the rest in 4x5, and haven't needed to push it yet, so this is a first time, and I was only looking to get some insight, use the info from what others have experienced to form a basis ... if 4 different photographers all said "well I found the listed ilford times to be a little short and had to go further by 2-6 minutes) then I have some BASIS to start with... so I don't have to start at 20 minutes and maybe start at 22... for example... the low end of the 4 photographers experienced time listings.... and go from there ... rather than go with ilford times which can be wrong for pushed films ... and completely have a botched roll ... why do that to myself when I can simply learn from those who have come before me ...
