Do digital cameras suffer from reciprocity failure?
Do digital cameras suffer from reciprocity failure?
Nope. Film breaks down from reciprocity; digital breaks down from noise. Different cameras behave rather differently in this respect. Most can manage 30 seconds with little quality loss, some can do up to several minutes, and a very few can go as long as a half an hour.
What ISO is FP4?

What is the difference between Ilford FP4 and HP5?
HP5 gives you the two stop speed advantage, but FP4 gives you finer grain. Having said that, for a 400 ISO film, HP5 has reasonably fine grain. I’d say use both. When and if you need the speed, use the HP5, and when you have a “slower” subject and more time, use the FP4.
What is reciprocity failure?
Reciprocity failure is what happens when, at longer exposures (generally shutter speeds of 1 second or more), the law of reciprocity (you guessed it!) fails! Over the course of a long exposure, the chemicals in the film emulsion lose their potency and become less sensitive to light as a result.
