    Re: Linhof Crests-Counterfeits?

    Not sure about the Linhof crest, but the new badges supplied by Mercedes are plastic when the old ones were metal. I found this out with the Mercedes SL I'm currently restoring.

    Re: Canham DLC45 Bellows Damage

    That looks like a huge bellows for a 75mm lens. Unless you are doing macro or planning on using 300mm and longer non-tele lenses, you might consider getting a shorter or even bag bellows.

    Re: DIY Sensitometer

    The most difficult part can be getting even exposure across the field. Did you do a test exposure with ND filter only and check edge vs center. If it is not even, you could figure where each step...
  5. Re: 305 G-Claron As W.A. 11x14 Enlarger Lens?

    Everything is a trade off. If the diffusion material is too close to the negative, any imperfection or dust might show in the print. A pragmatic approach would be to ignore an inch or so around the...
  6. Re: 305 G-Claron As W.A. 11x14 Enlarger Lens?

    If it covers 11x14 at infinity it would have a lot of promise to work on your enlarger. Due to the angle of the rays at the edges of the frame and the distance from your light source to negative, you...

    "Landscape" lens, so is that a cemented doublet? Is there some aperture mechanism in the snout?

    All my 8x10 exhibit bowing due to the tension of the light trap. Maybe your holders exhibiting no bowing have faulty light traps.

    I shoot almost all my 4x5 with a 150 lens. I can't tell what posts are sarcasm or not.
  11. Re: What’s your most “unpopular” opinion about LF?

    In the big picture of things, large format photography is not very common. Likewise nothing mentioned here matters.

    Re: formats, focal length and perspective

    Difficult but not impossible to get an idea of film format. As magnification increases, Dof decreases. Very shallow Dof of large objects cannot be achieved with small film formats.

    Re: Cheap 4X5 Cameras are Everywhere

    The only way to expose 4x5 is with a 4x5 camera. So a 4x5 camera would only be useless to a non-photographer, or someone too lazy to use it for what it was intended ( to expose 4x5).

    Re: How to learn a type of film?

    "Knowing" the film is knowing how it prints and how it responds to your meter settings. The best way to rapidly learn is to print the images the night they were exposed.

    Anyone trying to measure the shutterspeed of a leaf shutter needs to know how an aperture (shutter's iris or any aperture produced by the device) affects the results.

    The correction is real and well known, but there isn’t film fast enough for the situation to arise in most large format photography.
