Hey all,
So I'm posting this here for lack of a better place. However, since it's from 1902 it undoubtedly deals with large format, right? Ok, good....
This article is from the NY Times archive. It's a quick read about a liquid filled lens invented by Dr. Edward F. Grun of Brighton, England and how it permits shorter exposure, low light photography.... "Never before in photographic history has there been a lens so rapid as this."!
I found this article very intriguing, and the mention about increasing the speed surprised me. I came across this article while searching for liquid filled lens stuff, mainly in hopes of learning more about the panoramic abilities exploited by Thomas Sutton and his water filled, spherical lens (2nd link below).
Would the speed be increased in the same way that "modern" multi-coated lenses have decreased transmission losses in lenses? I'm familiar with the concept that air-to-glass surfaces result in lost transmission, and how Ansel Adam's encourages one to find an effective f-stop, due to these losses.
So I'm just curious, could this be the first example of lens coatings?
Thanks so much!
