Two films in one! Firstly the bad news: This is not a black and white film for purists who love the deep black and the clean white. But there is also good news: it can be developed in C41-process! Therefore the development of this film is as affordable as the one of colour films!
You can have it developed either as “normal” black and white film or as sepia toned film. I put “normal” in quotation marks because there is still a tiny colour cast which can reach from a greenish to a slight sepia tone.
Although you won’t get strong and clear black and white contrasts with the Ilford XP2, these tones can be appealing for several motives too.
In both cases it often depends on the drugstore or photolab how deep the colour cast or the sepia tone will turn out.
As this film has a speed of 400 ISO, you can use it for bad weather conditions or indoor shoots (all my sample photos were taken on days with a cloudy sky). And in my opinion you shouldn’t overuse it on sunny days when you want to have them developed with sepia tone. Then sometimes the sepia tone can turn out with too much orange in it (still depends how this film is being handled and processed) which looks a bit artificial and unnatural to me.
