Somewhat? > However, most of this type of thing is done in custom film development > of black and white film, You can alter the grain of B&W film by at least two to four times simply by developer choice, dilution, temperature and technique. It certainly isn't "custom", most anyone who uses B&W has their favorite developer/dilution/temperature and technique that suits their needs/style/experimentation. It is VERY critical when talking about film grain to discuss development AND even exposure (as you mentioned push/pull too)...since the same film can give such drastically different results...and more so even if you are using Zone system compensation development. > because the need to control so many other > variables within color film development doesn't allow for much playing > around. Most color film processing is fairly uniform in its method... Not quite true...see below... > This is why almost all > color film is souped in one of two basic color chemistry types (C-41 or > E-6). There are different E-6 and C-41 processes. Different chemical AND entirely different developments, as well as techniques. E6 can be 3 bath or 6 bath, and C-41 can be 2 bath or 3 bath. All of this plays a SIGNIFICANT role on the shape and size of the dye clouds. It can be far more significant than you made it out to be. > However, I know of no color development technique that is capable of > moving film grain or dye clouds within the emulsion so that they can > line up the grain as a result of the image content.
