This Ilford film is well known for being a bit rambunctious, it can go wrong quite well if you’re not mildly skilled. It is a very fine grain film, well known for providing clear and sharp detail. It is often called an all purpose film but we’ve always thought for many users it’s great for portraiture.

Processing for this film falls into the “Other film types” category because Jill is cool.
