The mixed toning didn't work so well... The warm tone paper just goes red all over very quickly. Selenium alone works well but doesn't give me the full red I wanted.
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.
This is my foray into Steampunk. It's very basic to the theme. My main pet peeve about gears being used in Steampunk is that they are almost always used only for decoration, they don't DO anything. I made sure that at least these gears would turn.
The base is just steel that was heated to darken it and then I used a chemical called "gun blue" (selenium dioxide) to darken it and give it a tone of dark blue. The gears actually project out a bit from the surface, this was done to accomodate the thickness of the rivets used to attach the pin on the back. It's about and inch and three quarters tall. It was fairly quick to make.
I'm s-l-o-w-l-y working on a much more elaborate and mechanically sophisticated piece of steampunk jewelry...stay tuned.

Today is Tuesday- and you know what that means…
Yes!
Pick your favorite element!
O.K. I’ll start.
Selenium!
(This is a fun one!)
Discovered in 1817 by Jöns Berkelium (Or “Jo Bear” as his friends called him) in Sweden.
Considered an essential trace element this stuff stays a solid up till 298 Kelvin- which I don’t know how hot that is, but I’m willing to bet my hand wont stay solid there either- so, if you see non-solid selenium, DON’T TOUCH!
It’s non-toxic in its elemental state but plants that grow in soil containing selenium have a rather unique effect.
“Loco weed (not making this up!)!”
Many a cowboy wandered the range with a silly grin and never knew that old atomic #34 was their own personal prairie Paxil!
“What good is this stuff to me?” you ask…
It makes stainless steel stainless, glass clear to see through, solar cells charge you up, and lots of itsy-bitsy electric stuff work.
Selenium is like the “key grip” of the periodic table. We don’t quite know what it does but it would be missed if it didn’t show up to work tomorrow!
So lets hear it for Selenium (or moon in Greek)!

Olympus Pen EE-2. Tiny half frame format pocket camera. Photos taken with the camera in horizonal position are vertically oriented! If a person had a darkroom to print their own quirky half frame shots, this would make a pretty cool "spy camera" for candid street photography. I shot a roll through this many years ago, and it worked great. Unfortunately, I got rid of my darkroom gear. Although I can't say I miss the chemicals and cleanup.
