  1. Re: Which lenses did Carleton Watkins use in 1861 for his mammoth plate camera

    In case anyone is interested, there is a contemporary report (August 15th 1863) on the Globe lens here: https://archive.rps.org/archive/volume-8/724646-volume-8-page-169?q=Grubb%20globe (and complete...
  2. Re: Which lenses did Carleton Watkins use in 1861 for his mammoth plate camera

    Fascinating. Looks like I need to do more digging. And FWIW one of the things I have found out is that patent law in Britain changed in 1852 making it easier to patent inventions. I suspect that this...
  3. Re: Which lenses did Carleton Watkins use in 1861 for his mammoth plate camera

    Well, sometimes the photographer was very helpful. Samuel Bourne of Simla shot snowscapes in the Himalayas in 1865, and at 18,600 feet (highest altitude for photography at the time) and noted in his...
  4. Re: Which lenses did Carleton Watkins use in 1861 for his mammoth plate camera

    The problem from my point of view is that there is information which mentions specific lenses but I find it difficult to find any confirmation of any claims. My interest is trying to see how...
  5. Re: Which lenses did Carleton Watkins use in 1861 for his mammoth plate camera

    Yes, but. the Harrison and Schnitzer wasn't patented until 1862 and Dallmeyer only started making lenses in late 1860 (mostly stereo from what I can find out so far and his Triple Achromat seems to...

    I'm currently researching a number of photographers and trying to tie them into to the existent optical technology of their time. Whilst this question has been asked before, I'm interested in what...

    Re: Identifying Bellows Peco Universal III

    I spoke to someone at custombellows.co.uk about a Gandolfi bellows I needed. "we used to make them for Gandolfi" he said "which model, we may have it from stock?". I described it and said I'd pop the...

    Thanks but I'm at 1863/4 so far but just wondering if that was the first date?
  9. Who first used Helical Focusing for a photo lens?

    An odd question I know, but does anyone know who first used a helicoid to focus a photographic lens and when?

    Re: Quarantine Pictures Any Format

    Fabulous weather here in Scotland, but staying in the garden. Time to dig out a camera nearing being usable (new bellows, lens mounted) and even if I can't use it yet, it is looking nice.

    Both look modified to me. It would be essential to check that both have the serial number micro-engraved on the lens glass in order to determine just how unoriginal either actually is.
