Ilford FP4 Plus 125 is a low-speed black-and-white film with fine grain and moderate to high contrast. This film is great for people who like the look of HP5+ but are interested in a lower speed option that will have finer grain and slightly higher sharpness. 
 
We recommend rating FP4 Plus 125 at box speed or slightly lower if you like a little more contrast and shadow detail in your images.
