The only time I tried it, I used FP4+ and Microphen. I didn't like the general results: although great at EI64, the film is grainy at its box speed, and more after the EI200 underexposure, and even more after Microphen, so I quit. That didn't look fine with the 28mm.
This time, I have to do it until I like it with any ISO100 film. I photograph mainly at EI640 with 35, 40 and 50mm lenses stopped down for small format handheld photography. I used to consider my 28mm close to 35's if we talk about DOF and zone focusing behaviour, but it is a lot more capable than 35mm lenses: I can get with it, more or less the same DOF of my 35's but with an aperture a stop and a half wider.
This means the 28 allows me to use -at least in theory- ISO100 films instead of ISO400 films.
Using ISO400 films at EI200 is not the optimal option in this case, because 1) 95% of the images will be soft overcast light, so the slight push is a better tonal option than the sometimes too flat ISO400 at 200 tonality when light is soft, and 2) the 28mm has a wide vision, so finer grain and higher resolving power makes more sense than bigger ISO400 grain, which can often -for some scenes- produce a certain lack of definition (compared to normal lenses) because the 28 compresses so much visual information inside the frame.
I never tried any other ISO100 film at 200, and this time I'll pick a film and a developer, and I'll use them for many years as my street ISO100 film, something I have never tried in a stable way.
Have you tried to use ISO100 films at 200?
I'm open to all films, not only TMX and Delta...
What would you say about developers, considering this is 35mm and darkroom printing?
Thanks everyone.
