    Curious about Wolcott's Mirror Camera - Old Daguerrotype lens question...

    Howdy,

    I'm curious how a lens/camera like this would work. Any pictures out there?

    "The world’s first studio system also included the most unusual camera. Alexander Wolcott patented a lensless camera on May 8, 1840, that was based on designs adopted by the scientific community for celestial telescopes. By replacing the lens with a highly polished concave mirror of speculum metal, Wolcott was able to create a faster camera suitable for portraiture."

    The plate was positioned where the secondary mirror would be in a reflector telescope.

    http://en.wikipedia.org/wiki/Reflect...cope#Gregorian Ok, that makes sense!

    So would there have been some anaomaly present in the image, similar to the "donut-boke" in a catadioptric lens? Are there any images around that were taken with this lens?

    Thanks for the response.

    Wow, Andrew K, thanks for that link! f/1.7 is quite impressive; no wonder it was such a boon for the slow daguerrotype.
