St Johnsbury, Vermont: Agfa APX 400 Test.

Back in 1990, I got a good deal on a 100 foot roll of Agfa 400 speed black & white film. I took quite a few photos with this, mostly of street scenes in San Francisco, and processed it in D76 1-1, much the way I would have processed Kodak Tri-X.

That was a mistake.

Fast forward 30 years and I thought I’d give Agfa 400 black & white another go.

This time I used a more refined process.

On April 12, 2020, Kris Sabbatino and I visited St. Johnsbury, Vermont, where we made a variety of photos around the former Maine Central truss bridge, located at the far west end of the old Mountain Division. I worked primarily with 90mm and 50mm Nikon lenses. The light was dull April overcast, which I thought would be a good test for Agfa 400.

Since I didn’t have access to my processing equipment and chemistry, I wasn’t able to develop the film until recently, but last weekend I finally souped the Agfa. I decided to try Rodinal Special (NOT to be confused with Rodinal) which is formulated for higher speed emulsions.

Before introducing the Rodinal Special (mixed 1-25), I presoaked the film for 5 minutes at 70 F in a very dilute bath of HC110 (mixed 1-300 with water and a drop of Photoflo-wetting agent). This was followed by the main development using my Rodinal Special mix for 4 minutes 30 seconds at 68 F; stop bath; twin fixer baths; rinse; permawash; first wash; selenium toner mixed 1-9 for 8 minutes; rinse and final wash.

There were a few hiccups in the washing. And as a result I ended up with precipitate on the negatives, so I ended up repeating the wash cycle yesterday morning, then soaked the negatives in distilled water with a drop of Photoflo before re-drying and scanning.

Now for the judgement. . . .

Striving for Tonality.

Last month I made this photo of a tram near its terminus in Basel, Switzerland.

To achieve deeper tones, I’ve adjusted my photographic process, shortening the development time, then boosting highlights by toning the negatives after development.

Working with my Nikon N90S with f2.0 35mm lens, I exposed a roll of Ilford HP5, rating it at 320 ISO. I processed the film in Agfa (formula) Rodinal Special (mixed 1-30 with water) for 3 minutes 25 seconds at 68 degrees F.

By design, this resulted in acceptable negatives, slightly on thin (light) side. Then, after fixing (two stage) and a thorough 10 minute rinse, I toned the negatives in selenium (using a 1-9 mix) for nine minutes with regular agitation.

Selenium toner is poisonous, so I wear latex gloves and perform the toning outside to avoid breathing the fumes, and pre-rinse the film prior to bringing it back inside.

Toning the negatives in this way boosts the highlights, giving the images a slightly silvery glow, while improving archival stability.

For this photo, I made some additional changes in post processing.

After scanning, I imported the file to Lightroom, and digitally lowered the contrast and highlight density of the sky-area in the top 1/3 of the frame.

My intent was to produce an image with a darker moody tonality and glistening highlights. I wonder if this will translate to the internet well?

 

Agfa Rodinal Special and selenium toners can be purchased from Freestyle in California, (see: http://www.freestylephoto.biz).
