  1. Re: Masking a Ground Glass for Cinema Aspect Ratios

    The easiest way is to create framelines in indesign or photoshop and print them onto clear acetate. That can then be placed over the back of the groundglass under the spring retainers. If the odd...

    You really want to live in Idaho with all the mad anti-govt nuts, EOTW preppers, and mormons that are too Mormon for Utah? I like Idaho to visit.

  6. Re: How much bellow draw needed for 30" lens for 14xx17

    Use the thin lens equation.

    (1/object distance)+(1/image distance)=(1/focal length)

    1/O+1/42=1/30

    Works out to O=105 so you can focus that 30" lens down to 105" (8'9") from the lensboard....

    Re: Would this make a good loupe?

    I'm one of those. 8x will do fine, though, and may even be the better choice for 4x5 where one expects to enlarge more than from larger negatives. 4x doesn't feel like enough to me.

    Re: Still Life Lenses for 8x10

    Perhaps one of the g-clarons would fit the bill if you want a very sharp lens. There is a 210mm, a 240mm, and a 270mm. All three will cover easily at 1:1. The 210 just covers at infinity. The 270mm...

    Your idea is similar to a couple types of shutters used in high speed photography. That small amount of light leak is a small but constant problem.

    You could just curtain off an area with black plastic dropcloth material. That will black out a small area easily and cheaply and act as a bit of dust buffer, too.

    Re: Condenser lens in a snoot?

    Look up a “source 4” fixture. It’s essentially that. You can put patterns in the lamp itself and focus them to get hard or soft edges.
