    Re: Making lemonade

    Ed, the Foveon sensors are intriguing, but any digital camera I invest in also needs to be able to photograph my kids sporting activities, and there a DSLR has distinct advantages. The Sigma cameras...

    Re: Making lemonade

    An update. Still using LF, but not really enough to put together coherent sets of images. I'm starting to feel at home with DSLR colour, although every now and then I'll try to take an image that...

    Re: B&W 4x5 film for indoor sports?

    I've had some good luck with panning at slower shutter speeds. I don't spray and pray, but I do discard 90–95% of what I take. I'm mostly photographing handball and basketball, where the faces and...
  4. Re: Should lead fishing weights be sewn in the hem of a dark cloth?

    FWIW, the curtain hem tape is less likely to break anything, because both the weight and any impact it has when windblown are spread out.

    That said, I use a Blackjacket, and greatly prefer it to a...

    Re: B&W 4x5 film for indoor sports?

    At 1/200 the blur will be 'artistic', even with kids. Or you'll have to stick to landings and balance poses. If you can bump the shutter speed up to 1/400 (Aero ektars are cheap) you will do much...
  6. Re: Should lead fishing weights be sewn in the hem of a dark cloth?

    Your seamstress may already have the kind of lead weight tape used for curtain hems. It comes in various grades of heavy, and is conveniently encapsulated in a cloth cover. Flexible, and easy to...

    Re: Sinar Shutter

    Many graphic arts lenses and older brass lenses have the flange at the back. They can often be mounted on a flat board.

    Norma-era coned lens boards are reasonably cheap, if you don't need the...

    The hood rotates in the holder, so aligning it with the standards/film edges is no problem at all.

    I don't know of there were later filter holders. I'm talking about the ones that look like a...

    Re: Need a very slow motor (like 1 RPM).

    Kumar, I don't think there are general answers to that. A lazy Susan usually has a bearing, so they spin quite freely. You would have to find a clock that can generate enough torque, but the torque...

    Butcher a clock. Use the second hand drive for 1 RPM. Change the photo-taking rate for other speeds.
