Exposure latitudes.

  • I've Googled and Yahood and haven't come up with an acceptable search.
    I know and understand the concept of exposure latitudes and also the theory of expose for the shadows and develop for the highlights. However the only film I remember the exposure latitude for is Tri-X... -2 to +5 stops and still produce a usable negative.

    Does anyone know of a table listing latitudes for some of the more common films (negs and positives) used today? In particular Plus-X, T-Max, FP4, HP5,
    Provia, Velvia, Portra, Ektachrome... I tend to like my shots a touch underexposed or at least printed a little on the dark side.

    Any ideas or information? Thanks,

    Dave


  • Do you mean how far off the exposure can be, and still get a decent print?

    I think it's going to be mostly opinion. I guess Tri-X over-exposed 5 stops may be usable, but I don't want to use it. In general I consider most neg film to have an exposure latitude of about 2 stops in either direction. The exception would be C41 BW, which might be able to pull off -3 to +4.

    I read people claiming to get 9 to 15 stops of full detail with some materials, techniques, etc... That's a whole lot of exposure latitude.
