Tracking the Light focus on creating photos and this post is about the nuts and bolts of working with black & white film, and pursuing means to refine the process.<\/p>\n

What better way to spend a damp, windy snowy day, then to expose and process black & white film in new ways?<\/p>\n

I\u2019d read about \u2018stand processing,\u2019 but I\u2019d never tried it.<\/p>\n

Stand processing uses developer at very low-concentration with virtually no agitation for very long process times.<\/p>\n

Among the potential advantages of stand processing is greater tonality with exceptional highlight and shadow detail. A secondary benefit is that it requires much less developer. Also, I wondered if I could better control granularity by eliminating the effects of agitation (the answer from this test was: no).<\/p>\n

I\u2019d previously experimented with Foma Retropan, a modern film rated at 320 that emulates the effects of traditional emulsions. For those photos I processed the film in Foma\u2019s specially formulated Retro developer. I found the negatives to be grainy, but offering a distinctive tonality with soft highlights.<\/p>\n

See: Retropan on the Rails; Experiments with My second Roll of Foma\u2019s 320 ISO Black & White film<\/a>. [https:\/\/wp.me\/p2BVuC-4Bj] and<\/p>\n

Below are some examples of Retropan using stand development in Agfa Rodinal (mixed 1:100 with water) for 40 minutes, 10 seconds agitation at beginning of development, and again at the end. Development temp 74 F.<\/p>\n

For comparison, a couple of hours later \u00a0I also exposed more Retropan and processed this in Agfa Rodinal Special (as distinct from ordinary Rodinal) but with agitation and short process times; one batch (mixed at 1:32) at 68F for 4 minutes;<\/p>\n

\"\"<\/a>

A second batch (mixed at 1:32) at 70F for 70 minutes. I then toned these negatives for 9 minutes in a selenium solution to boost highlight detail.<\/p>\n

Retropan 7 minutes (70F) Agfa Rodinal Special with 10 second agitation every 30 seconds, plus 9 minutes selenium toner. 50mm lens<\/figcaption><\/figure>\n

This is a work in progress and I have no formal conclusions, but makes for some interesting images.<\/p>\n
