    Re: New Security Measures at B&H

    I've had a problem with B&H requiring a signature for lenses they ship. I live in a condo and the delivery person is supposed to use our intercom system to let me know he is here, but he doesn't...

    Re: DOF question 35mm vs. 4x5

    Jeff Conrad's discussion does a good job of explaining what is going on, and anyone who really want to understand the subject should read his article.

    Re: Flowers Anyone?

    I find it frustrating using my view camera to photograph individual flowers. The problem is that if you get close enough, you have very little depth of field at feasible apertures. (If you stop...
  4. Thread: Loupes

    Re: Loupes

    I agree. If the loupe magnifies too strongly, you will end up focusing on surface features of your ground glass instead of on your image.

    I use the near point-far point method, and my images...

    Re: Spot meter recommendations

    I recommend either the Pentax Digital or the Pentax V. If you can find either used at a good price, grab it.

    Re: 4X5 dgitital backs

    I've always used a dark t-sirt. The neck goes over the rear standard and I stick my head in through the other end. If necessary I can stick my arms through the armholes to reach controls.

    I don't think it much matters, but if the emulsion side is up, you will reverse left and right. Of course you can correct for that in the scanner settings.
