    This is pretty much what I do. I cover the lens, pull the dark slide, try to estimate the exposure as closely as I can and then cover the lens before reinserting the dark slide. I'm pretty sure that's how I did this one attached (I'd check my log, but it's in the truck)

    cheers

    No problem Charlie - and thanks for the kind words!

    BTW, if you put in a drawstring, the lens sock makes a good lens case, as well.

    I made a drop shutter for a Cokin P filter holder. Works like a charm.

    I take it that once you have a mechanism in place then you have some control over shutter speed by altering the slit width, like a focal plane shutter?

    Not at all. Shutter speeds are only accurate from 1 second an up.

    The big advantage is that you can use filters in front of the lens. That's impossible with the sock shutter idea.

    Not really impossible.

    The quoted statement MAY be correct if one is using Gel or plastic filters mounted in front of the lens.

    Obviously, it is not a correct statement if one uses screw-in glass filters.

    Also it is not a correct statement if one has Apo Nikkor and Apo Ronar lenses or other process lenses (like I do) which incorporate a filter insert slot in the lens barrel at the center of the lens and filter inserts (slips).

    Might checkthis link out. A bit slow to load (real slow if dial up) but really a good to see how the process works...he uses a sock for a shutter.

    Jim's "wrist flick" shutter works great.

    I have used it outdoors with up to 400 speed film with little trouble. It does take a little practice to get started, but no extra equipment is needed - just two dark slides.

    I like to shoot really slow and I rarely bring anything to use as a shutter other than the dark cloth. I just wad it up and cover the lens, then pull the slide and slowly slide the cloth away from the lens. You can hold it an inch or 2 in front of the lens and you won't get any exposuse. Then remove and expose for your desired time. Its very easy to get down to 1 sec exposures but I like to shoot very slow, somewhere in the 10 sec range and up into the minutes. I enjoy having trees blowing in the wind to soften an image that would otherwise be fully sharp. I shoot alot in overcast but also in the sun with 25 speed film I am frequently using a red filter or a dark neutral density to slow down the film. Om the other hand with the huge camera (30x40cm) my film is iso 3 and I dont have to do anything to slow it down.
