Delta 3200: the developer deserves a test roll

Ilford Delta 3200 is a fast black-and-white film for photographs where light is scarce or the subject refuses to stay still. Choosing it is only half the decision. The developer, the chemical that turns the exposed film’s latent image into a visible negative, is the other half. Before deciding whether you like this film, it helps to know how it was processed.

That is the thread running through Dmitri’s six-year review for Analog.Cafe. He describes six years of coming back to Delta 3200, roll after roll. That makes the review interesting as an account of living with a film: returning to it, changing the processing, and finding uses for its sensitivity.

Start with the developer you know

In Dmitri’s Analog.Cafe account, the practical setting is British Columbia’s dark, wet winters. He also uses the film for pets, where a fast shutter and enough depth of field help keep a moving subject recognisable. His camera list spans the Hasselblad XPan, Nikonos V, Nikon F3 and Voigtländer Vitessa A. This is experience gathered across several cameras, not one afternoon’s first impression.

The processing list includes Rodinal at 3200, Rodinal at EI 1600 and Ilford DD-X at 3200. Those entries raise two questions for an experienced photographer: what changes when you choose another developer, and what changes when you give the film more exposure? The list alone cannot name a winner for grain or show that the comparisons used matched conditions. Look at Dmitri’s samples and conclusions in the original before borrowing a preference.

A contrasting impulse appears in Jack Baty’s 20 October post. After years of HC-110, he tried the staining developer 510 Pyro on HP5. He reports mixing it at 1:100 using 4 ml, with a supplied oral syringe helping to measure the syrupy concentrate. He also cites a six-year shelf life after opening. That is a handy detail for anyone who develops only occasionally, though his post supplies no storage test. His experience concerns HP5: it gives a reason to investigate a developer, not a Delta 3200 result.

Give extra exposure a specific job

Dmitri’s two Rodinal entries are the most instructive pair, because the developer stays the same while the exposure index changes. EI means exposure index, the speed setting you choose for metering. Setting 1600 instead of 3200 asks for one stop more exposure. In the same light, that means a slower shutter or a wider aperture.

That trade matters if your reason for loading Delta 3200 was a moving animal or a dim room. Before lowering the setting, decide what you hope to gain. Shadow detail is a sensible question: can you tell dark fabric from its background, or see what you wanted beneath a table? Judge texture separately, so that an improvement in one part of the picture does not get credit for improving everything.

There is a caution in Rosie’s Delta 400 processing note on Bluesky. Rosie was trying Bellini EuroHC as an alternative to a beloved Ilfotec HC, while also wondering whether the meter had been off. A later post specifies EuroHC at 1+31. The dilution makes the record more complete, but the possible exposure problem still complicates any judgement about the new developer. It is a different film, with a familiar lesson about keeping notes.

Make the next roll answer one question

If texture is your concern, begin with a developer comparison. Keep the camera, lens, metering method and exposure index the same. Photograph repeatable subjects in steady light across separate rolls, including the shadows, midtones and highlights you care about in the finished photograph. Record enough to recognise each setup later.

Use established processing instructions for each developer and exposure index. Keep notes on dilution, temperature, time and agitation; an unexplained difference in handling makes the comparison harder to read. Wear gloves and eye protection, work with ventilation, and collect used fixer for proper disposal rather than pouring it into drains where local rules prohibit that.

Judge the results at the size you actually use. When scanning, keep sharpening, noise reduction and output size consistent. Compare the full photograph as well as an equally enlarged detail. If you print in the darkroom, compare at your usual enlargement, giving each negative a suitable printing exposure. A magnified patch of grain answers a narrower question than a finished print.

Once you have chosen a developer, test exposure index while keeping that developer fixed. Development instructions may also change with the chosen index, so record those changes rather than calling it a pure exposure test. What you want at the end is a repeatable combination for your own photographs.

Open Dmitri’s review, find the developer you already use, and make your next Delta 3200 roll answer one question.
