Determing what is the best type of development is a highly subjective decision but the examples you provided are are quite appropriate. In addition I would add that semi-stand and stand might be recommended for situations where you need to milk every bit of shadow density possible out of the negatives. And Steve Sherman uses semi-stand to enhance micro-contrast in mid-tone areas when working with subjects of very low overall contrast.

However, avoid semi-stand or stand with any type of subject that contains a lot of large even tonal areas, and even more so subjects that contain large areas of even shadow areas adjacent to large areas of mid-tones or highlights. The only exception would be if you are willing to make two or three negatives of the scene and are willing to sacrifice one of them for the very special qualities you might get with stand. But be aware that there are always some risk with stand development.

Hi Sandy:

During a search on reduced agitation techniques, I came across this thread. The way I understand the technique, is to give increased contrast to a negative of a low contrast scene, correct? When I read your post on the dilutions you use for each agitation type, I thought you meant that to reach (for example) a contrast of 3 times your normal, you would use Extreme Minimal agitation and a dilution of 1:1.5:200 (for some unmentioned time). But you actually mean that the same contrast is maintained by making the dilution stated, and developing Extreme Minimal for 3 time the normal time. I don't understand why a person would bother, and not just do normal development, if they're wanting to maintain the same contrast in the neg. Or am I misunderstanding this second post, and had it right initially (I'm trying to find times and dilutions to try reduced agitation with FP4+)? I read also that reduced agitation with Pyrocat HD will give box speed for a film- is this true?

Thanks,
Tim
