    Re: Calumet c2n & infrared

    FWIW, its easy enough to make dark slides out of thin sheet brass from hobby stores. I did it for my 6x9 C2N roll film bacls as they were always breaking and cheaper to make from metal than buy new in plastic.
    Thanks,

    Don't worry about it, at normal shooting apertures it becomes a non-issue. The real issue is that the best IR film made is no longer available.

    How do you cut thin metal sheets without bending them? I've tried cutting aluminum for some other projects but getting a smooth cut was very difficult. Snips bend the metal, and a cutting wheel (like on a handheld rotary tool) makes an uneven and rough cut.

    As you may guess I have no experience with this at all.
