Head to head
Ilford HP5+ vs Ilford FP4+
Two Ilford classics that land in almost every shooter's bag at some point, and the choice usually comes down to one number: HP5+ runs at ISO 400, FP4+ at ISO 125. That gap is roughly a stop and a half, which decides whether you can shoot handheld in a dim cafe or whether you need a tripod by late afternoon. Everything else (both traditional cubic-grain emulsions, both forgiving in development, both cheap relative to color) flows downstream from that speed difference.
How they differ
HP5+ is the workhorse. The extra speed buys you faster shutter speeds and smaller apertures, and it takes a push beautifully, ISO 800 and 1600 are routine, 3200 is usable when you accept the grain. That grain is the trade: HP5+ is noticeably grainier and a touch lower in resolved detail, with broad, soft tonality that flatters skin and street scenes. FP4+ at 125 is finer grained, sharper, and holds a longer, more delicate tonal scale, so prints from a 35mm FP4+ negative look cleaner enlarged and a medium-format FP4+ frame is genuinely luscious.
In the field the difference is shutter speed and light. FP4+ wants daylight, studio strobe, or a tripod; in flat overcast or indoors you run out of speed quickly. HP5+ shrugs that off. Both develop in the same chemistry (HC-110, ID-11, Rodinal, DD-X all work), both have wide exposure latitude that rewards overexposing a little, and pricing is close, with HP5+ usually a hair cheaper per roll and the more widely stocked of the two. Availability is good for both, though HP5+ tends to be the one any shop will have on the shelf.
Choose Ilford HP5+
Reach for HP5+ when light is unpredictable or low: street, documentary, concerts, weddings, anything handheld indoors or near dusk. It is the better pick for beginners because the speed covers metering mistakes, and it is the obvious choice if you want to push to 800 or 1600. If you shoot 35mm and care more about getting the frame than about pristine grain, this is your everyday stock.

Pick FP4+ when you control the light and want the cleanest result: landscapes on a tripod, portraits with strobe, still life, architecture, any careful work where you can afford the slower speed. It shines in medium and large format, where the fine grain and long tonal range turn into big, smooth enlargements. Choose it when the print quality matters more than shooting speed.

Neither is better, they solve different problems. If you can only stock one and you shoot varied conditions, HP5+ is the safer single choice for its speed and latitude. If your work is deliberate and well lit, FP4+ rewards you with finer grain and sweeter tones. Plenty of photographers simply carry both and load by the light.
