  1. Re: New Lens Scale: How To Convert Milliseconds To Standard Camera Fractions?

    If you're shooting with negative film in either B&W or color, there's usually lots of latitude, so a half stop overexposure is no problem. Negative films will often benefit from the extra exposure,...
  2. Re: New Lens Scale: How To Convert Milliseconds To Standard Camera Fractions?

    Your shutter speeds seem to be around half a stop slow throughout the range, but 1/400 is pretty close to 1/250. It's not exactly half a stop, but close enough that it won't matter. Depending on...

    Re: Ansels The Negative

  5. Re: Is this a Linhof Technika III lens board or something else?

    The boards for a IV, V, or Master all have a big chamfer on the lower corners. The III boards have plain 90 degree corners. That's the easiest way to identify them by sight.
  6. Re: why they remove the price after an item is sold ?

    It's a polite way of saying the discussion is over. If it just says "sold", people are going to be asking if it sold for the asked for price, or something lower/higher, and this could go on for...
  7. Re: why they remove the price after an item is sold ?

    If the seller removes the original asking price, then there's no doubt that the item is no longer for sale. It may not be obvious that an item is already sold at first glance, and this may lead to...
