Ilford HP5 Plus 400
How this look was derived, and why every control does what it does. The settings themselves are in the pack.

The film
Ilford HP5 Plus 400 is the classic British medium-speed B&W, the reportage/documentary counterpart to Tri-X. It's known for strong, balanced tonality, even (traditional cubic) grain that distributes smoothly, medium contrast, and deep shadows that stay dark ("lets shadows be shadows"). Very forgiving and push-friendly. Flexible across lighting.
The look in one line
Balanced, forgiving reportage B&W, even visible grain, medium contrast, rich natural shadows.
Real-scan validation (1 scan)
Analysed from Wikimedia Commons (analysis-only): a foggy skyline. Prominent, even, structured grain across the smooth grey fog; medium contrast with buildings holding as solid dark-grey-to-black masses; gentle highlight roll-— in the mist. Confirmed: even visible grain → Grain —/—; balanced medium contrast → — + —; deep natural shadows → Shadow —. (Single scan → one more pass recommended for portrait/sunlit conditions.)
vs the other B&W originals
HP5 is the middle ground: - Grittier/heavier than Acros (which is fine/smooth), but - Smoother and lower-contrast than Tri-X (which is clumpy-grained, high-contrast, Clarity —). HP5 keeps —. It's a smooth, balanced stock, not a gritty one.
Datasheet confirmation (Harman/Ilford HP5 Plus technical sheet, fetched & extracted)
- "High speed, fine grain, medium contrast": the sheet's own words → confirms — (medium contrast) and grain visible-but-not-clumpy.
- Push range documented to EI 3200/36 ("responds well to push-processing") → confirms the high ISO ceiling; grain/contrast rise gracefully with EI.
- Development aims produce "negatives of average contrast suitable for printing in all enlargers" → HP5's balanced curve is by design; our Shadow —carries the "lets shadows be shadows" depth without inflating overall contrast.
Validation tier
Datasheet (extracted) + characteristic + scan-validated (1 condition). Next pass: add sunlit + portrait scans, and confirm grain size (—/— vs —/—) against a well-exposed daylight frame.
