    Fomapan T800 was an iso 800 B&W film. Discontinued in 2001 due to a lack of interest.

    Best overall iso 800 B&W film is the Neopan 1600 from Fuji. In most common developers an effective DIN/E.I. around iso 800.
    With some speed enhanced developers (e.g. SPUR SLD) around iso 1000.

    What about chromogenics? Anything which can be shot at iso 800 and developed normally at labs?

    The chromogenic mono market is small enough as it is; demand for a grainier 800 would be negligible. Ilford considered a chromogenic for their ultra-high-speed film but made Delta 3200 instead, mostly (as I recall) because of static problems. Also, they reckoned most people who want an ultra-fast film woukd be able to (and would prefer to) develop it themselves.

    HP5 Plus is ISO 650 in speed increasing developers such as Microphen and as Robert says Fuji's 1600 is 800 in DD-X or the like. TMZ is ISO 800-1000 in most developerts and Delta 3200 is ISO 1000-1200 in most developers.

    Cheers,

    R.

    ISO versus EI

    There are no ISO 1.600 or ISO 3.200 films at all, only EI 1.600 and EI 3.200. Don't confuse ISO and EI. ISO has a very specific definition. EI is not defined at all - anything, however unrealistic, can just be called EI.

    I don't know any reason for this, but I have been more than happy
    with results using Ilford Delta 400 @800. You should try it.

    Also test 400TX. Excellent for interiors @ iso800 in D76 "c" formulation w/ some potassium bromide & iodide to hold max shadow detail, avoid overly-dense highlights. HP5+ pretty good as well.

    I suppose since "fast" mono films hold up so well upped just one stop, and you can easily drop the 1600s to 800, there's never been a market for iso800.

    Agree, using 0.1 above film density gave me 800 also with TMZ.
