First I recommend that you read Ilford's spiel here: http://www.ilfordphoto.com/products/...26+White+Films

I use mainly FP4+ and I can tell you that I get excellent results from it; it's very forgiving of exposure errors, especially overexposure. It's versatile and can be pushed to 400 ASA, or possibly higher. I find my exposures, metered with a hand-held Lunasix and exposed in my SQ-B and Yashica 124-G, and 35mm SLR, to be spot-on the 125 ASA / 22 DIN rated by Ilford - these guys make the film, they know what they're talking about! I don't faff around with 'personal film speed testing' - I'd rather take pictures! If exposed properly (meter and expose for shadows - film's exposure latitude is mostly in the area of over-exposure) the film can record a full range of shadow and highlight detail.

I develop exclusively in Ilford ID-11, which gives fine grain and excellent sharpness. Unless you're printing billboards or photographing black cats in coal cellars I don't think you'll be disappointed by FP4+. I cannot comment on HP5+ since I haven't used it for a few years.

I've got to agree with all of this. Being a relative youngster, I cut my teeth on FP4+ and love it! Like Kevs, I use it at box speed in both 35mm and 120 format. Really forgiving, can be pushed, pulled, played around with and has nice, fine grain etc. etc.

I also develop this film exclusively in ID-11 @ 1:1 - I feel to get slighly high acutance, but that's a "by-eye" estimate, nothing sensiometric!
