If you want an affordable B&W film that can be processed at most photo labs, Ilford XP2 Super 400 could be the one you need. It's a B&W film that can be developed using the C41 color processing.
For B&W film lovers, it is increasingly difficult to find photo labs that can develop traditional silver halide B&W films. And for those few that did, the prices can be exorbitant. Coupled with the fact that pure B&W film prices had been rising due to sky rocketing commodity prices, getting one’s fix of shooting B&W films can become prohibitively high.
Ilford XP2 Super 400 is an affordable B&W film that can be processed at most photo labs, as it can be processed in C41 type processing chemicals alongside color negative films. The film yields high contrast negatives and has an extremely wide exposure latitude, making it suitable for use in varied lighting conditions. Another reason I like to use XP2 Super is that it is sharp, fast, and produces relatively fine grain.
XP2 Super’s fast speed (ASA 400) means that it can be used indoors and in low lighting conditions. However, I mainly use the film outdoors for street photography.
It has been said that one can push or pull it 2-3 stops either way but I have yet to try it. Also, as it is essentially a C41 color film, one can scan the developed negatives using “color neg” mode and get surprised by the different color tones. Color tone varies depending on the processing and exposure.
Try out one roll and I bet you will not regret it!
