Not all of these +were great images, but they were products of many experiements +with film, developer, agitation, and dilution: + +* Semistand works well for most normal and even short SBR scenes + +* EMA is indicated when you have very flat mid-tone contrast, but + using it for normal SBRs can crank up the contrast in ways I do not + love, so it needs to be applied with restraint. Even in flat + lighting, too much agitation or not enough dilution can *really* + crank up mid-tone contrast in unpleasant (to me, anyway) ways. + +* *You Can Overdo A Good Thing Part 1*: Using EMA on highly textured + subjects can lead to a kind of gritty graphics art look that might + be an interesting aesthetic for some things but is overkill for + most. + +* *You Can Overdo A Good Thing Part 2*: High dilution does enhance + sharpness but it does so at the expense of visible grain. This is + not an issue for large format, and - depending on film - can be + managed for rollfilm, but it's a killer for 35mm (unless you like + that "sandy" Rodinal look). + +* Long SBRs present a challenge. If you develop conventionally using + N- discipline, you'll hold the whole dynamic range, but almost + always at the expense of contracting mid-tone contrast. You can use + semistand or even EMA to both hold down the highlights and keep + mid-tone contrast where it should be, BUT, you have to dilute more + for this to work properly on the highlights. This can cause he + aforementioned grain visiblity problem. This is a place where + Pyrocat-HD is quite helpful because the stain helps to mask grain + visibility. + + There are alternatives here that I have yet to explore: SLIMT, two + bath, and highly compensating developers all leap to mind. + + ## Updates New findings since the document first went live can be found below.
