We did a lot of the stand here and do this, touristy shots. The goal here was to get the water skier in the background.
This trail circled the entire lake, and met up with other branches. Needless to say I now have a great appreciation of Madison.
It is an AE rangefinder with around-the-lens selenium censor and has similar red flag thing as Olympus Trip 35, preventing the shutter when there is not enough light.
Some other specs (from manual) :
Asa : 10-200
Lens : Hexanon 40mm f/2.8-f/22
Shutter : Seiko 1/30s-1/250s
Flash sync at 1/30s.

I put this in this folder to compare a conventional print to the lith version. Most prefer this or a cold tone version. I like the lith...go figure....Forte Polywarmtone toned in selenium, 35mm Tri-x

The Gossen Bisix Lightmeter.
Up front there is a big selenium cell which powers the needle in the meter.
No battery needed !
There is only 1 range so i guess this was ment to be a low-cost meter designed for the amateur photographer.
The Filmsensivity scale goes from 12 ASA (12DIN) till 1600 ASA (33DIN).
The Shutterspeed Scale goes from 1/1000 till 15 Seconds.
The Aperture Scale from 2 till 22.
Small amounts of remaining selenium on steel loop oxidizes readily when heated and the vapor burns in contact with aerated butane flame with a bright blue flame, forming acidic fumes of selenium dioxide. Selenium does not continue to burn when the gas flame is removed.

I'm not entirely happy with this. I wanted a somewhat softer look. I may have sharpened too aggresively.

and another interesting article The Engineer vol 27-28 pg 118 1894
Seen and taken at Langstone with canon 7D2 and the 500mm prime. Yet to decide whether I prefer the tinted version or the original !
The colour has been leached from the berries by the red filter, and from the leaves by reflected infrared light. Albino holly?

Zeiss Ikon Vintage Test Lightmeters.
An retired repairman told me that these selenium cell powered lightmeters were used to check other "normal" lightmeters. That's all i know.
These meters clearly use the housing of the "normal" Ikophot model which was produced in the middle of the nineteen-fifthies.
A view on the front.
A partially Selenium toned Lith Print of Blackrock Cottage, Glencoe, Scotland.
The meta data suggestes the shot was made on a Nikon D70. It was however made witha Bronica ETRS with a 75mm lens. The original negative was made on Ilford Delta 400, rated at 200 and processed in Pyro developer.
The lith print was then made and subsequently photographed with a Nikon D70 to 'digitise' it for inclusion on Flickr.
