Retropan Test—Further Experiments with a New Emulsion.

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.

What better way to spend a damp, windy snowy day, then to expose and process black & white film in new ways?

I’d read about ‘stand processing,’ but I’d never tried it.

Stand processing uses developer at very low-concentration with virtually no agitation for very long process times.

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).

I’d 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’s specially formulated Retro developer. I found the negatives to be grainy, but offering a distinctive tonality with soft highlights.

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.

Retropan stand process for 40 minutes in Rodinal mixed 1 to 100 with water. 135mm lens.
Retropan stand process for 40 minutes in Rodinal mixed 1 to 100 with water. 24mm lens.

For comparison, a couple of hours later  I 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;

Retropan 4 minutes Agfa Rodinal Special with 10 second agitation every 30 seconds, plus 9 minutes selenium toner. 24mm lens.

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.

Retropan 7 minutes (70F) Agfa Rodinal Special with 10 second agitation every 30 seconds, plus 9 minutes selenium toner. 50mm lens

This is a work in progress and I have no formal conclusions, but makes for some interesting images.

    Amazing detail in that Wellington Monument long shot. You can check the individual bricks. Like one of the old plate images.

    I take it those photos are taken somewhere close to Phoenix Park (i.e. the Obelisk) – they don’t really look like a New England scene.

    Mind you – with the snow, its unusual enough for a Dublin scene too.
