    exposures longer than 1 second?

    All of my shutters max out at 1 second exposures.

    What do you guys do for exposures longer than 1 second?

    I had to do a 2sec exposure, and I think I just used the stop-setting where I press to open shutter, then press again to close. Although maybe for vibrations is better to set the cock to the one where you press to open the shutter, and let go to close it. In any event, I counted. Doesn't seem accurate at all. Do you guys use timers or something like that?

    Other possibility is to set he cock to 1 second, expose, then re-cock it and expose again. Although this seems to introduce the possibility of creating some fuzziness if you change the camera positioning at all.

    Thanks for any thoughts.

    I just count them out. When I go beyond 1 sec., I try to stop down an extra stop so that I'm in the 4 sec range, so I've more room for error. I generally shoot B&W and this technique serves me well. Even for the times when I shot trannies this still works for me, but I do bracket a bit.
    I trick that I learned from my father, when doing really long exposures, is to pull the dark slide out, put it in front of the lens, then open the shutter.

    Fuji Acros, if possible. And the second hand on my watch if necessary.

    I've been known to measure pinhole exposures in units of cigarettes.

    Exposures between 1-2 seconds are the worst because the accuracy of using the B setting is suspect. But stopping down to increase the time further could result in reciprocity issues if not anticipated. I use the BTZS software on a Palm and it has a timer function which helps time the multisecond exposures. If you have a solid tripod you could use multiple 1s exposures plus 1/2, 1/8, etc. as needed.

    I've done a few 2&3sec exposures in multiples of one seconds...carefully cocking and tripping the shutter each time. The prints are sharp but I guess its still a bit of a gamble using this method. If I though I was presented with a really killer image would I take the gamble, or would I opt for (B) & 1 anseladams 2anseladams?
