    If this is how you get off, you're in deep kimchi.

    I've been shooting long exposures on TriX and Shanghai 100 for about a year, paired up with a ND110 in the day and just stopping down at night, I've been taking 20min to 1 hour long exposures.

    I followed Kodak's suggestions for TriX, and for Shanghai I based it off TriX but realized it was much slower and now compensate accordingly.

    Now moving onto Velvia, longest so far was 10 minutes!

    Re: Reciprocity failure

    I like reciprocity failure -- approached properly, it gives one such a nice boost in contrast (B&W). My exposure times are usually in the minutes under the redwoods. I give just a little more exposure, then develop the heck out the negative for wonderful contrast and feeling of light for my carbon prints and platinum prints.
