Shooting Ilford HP5 at box speed, 800 and 3200: a practical comparison

HP5 Plus is the club film here — cheap enough to burn, forgiving enough to trust. But "you can shoot it at anything" gets repeated so often that we decided to actually test it. Three of us took three bodies into the Brecon Beacons for a weekend and ran the same scenes at box speed 400, at 800, and at 3200.

The setup

All rolls developed in Ilford DD-X: box speed at the standard 9 minutes, 800 at 12, and 3200 at 20 (all at 20°C, agitation ten seconds per minute). Same batches of chemistry, same tank, prints made at grade 2.5 on the same paper. As controlled as a club experiment gets.

At 400 the negatives are everything the datasheet promises: full shadow detail in the heather, gentle grain, highlights that shoulder off politely even in flat hill light. If you're printing 12x16 or bigger, box speed is where HP5 stays boring in the best way.

At 800 honestly? Almost free. Shadows lose a whisper of separation you'll only see printing low-key scenes, grain tightens slightly, and the extra shutter speed on a breezy summit is worth more than what you give up. Two of us now rate HP5 at 800 by default.

At 3200 it becomes a different, moodier film. Shadows go properly black — the drama is real and so is the loss. Grain turns gritty in an attractive, reportage way, and midtone contrast climbs. For twilight in Cwm Llwch it produced the most striking frames of the weekend; for sunny landscapes it's the wrong tool.

What we took home

Rate it 400 for prints that vanish into tonality, 800 for everyday walking-around, 3200 when the light has almost gone and you want the pictures to admit it. And write the speed on the canister the moment you rewind — one of our three test rolls spent a week as a mystery because nobody did.
