After my first attempt , I thought I'd better try a proper photograph. Shortly after dinner this week I grabbed my wife's roses and put them in a couple different locations in the living room to see what kind of light there was to use.
I used to "believe" St. Ansel when he would go into a tirade against William Mortensen. But the more I look, the more I like Mortensen's style. While these are not to be confused with Mortensen, I like the way these images begin to free me up from the strictures of St. Ansel.

My three German friends are (left to right):
1. Zeiss Ikon Super Ikonta 533/16 with 80mm coated Opton T* Tessar lens; classic medium format folding camera; it produces 6x6cm negatives. Note the leather bellows. It was last available new in 1954. Weight 1.4kg. More information at...
www.lumieresenboite.com/collection2.php?l=2&c=Zeiss_I...
2. Leica M6 Wetzlar with 35mm Carl Zeiss Biogon lens. A classic 35mm rangefinder camera which was available new from 1984 to 1998. This one is clothed in a Luigi leather case. More information at...
www.cameraquest.com/mguide.htm
3. Rolleiflex 2.8F Twin Lens Reflex (TLR) with 80mm Xenotar taking lens; produces 6x6cm medium format negatives. It was last available new in 1978 (UK). Weight 1.2kg. More information at..
www.geocities.com/heidoscop/tlrs2.htm
All are manual, mechanical film cameras with only one battery between them (in the M6 to power the light meter)! The light meters in the Super Ikonta and Rolleiflex don't need batteries. Also, no moving mirrors anywhere :-)
[Taken with a Canon 350D with Sigma 18-55mm f2.8 EX lens]
After the death of the Selenium cell about 2 hours prior and with a few exposures left, figured I would have some fun.
I think this was at f.22? It was a pretty damn hot, bright day.
Went up a mountain in 35+ degree heat, because the roads being closed to the ocean and after a 4 hour battle we reach the top of the Helderberg.
Young Jonathan fell victim to a severe case of sun induced lunacy and in a moment of wild abandon dropped his trousers baring all and sparing no one.
His white body reflected a light so intense and bright that it was reported to have been seen from over 120 km's away by a numerous farmers and farmhands whose names are being withheld.
Very sturdy, simple camera. Came with a Prontor SLK Spezial shutter, speeds from 1 to the 1/300 + B. The lens is a coated Pantar 45mm f/2.8. A Selenium cell is coupled to the aperture ring.
This example's shutter fired fine in the store, a couple times at home and then it decided to miss-fire. The shutter goes off while winding. (sigh) Oh, well, it'll look good on the shelf till I can putter with it's repair.

The design of the Kiev-4 is firmly based on that of a classic pre-war German camera Zeiss Contax III. Kiev-4M is the modernized model of Kiev-4.
Arsenal: Zavod Arsenal (= Завод "Арсенал"), Kiev,Ukraine. Arsenal is one of the oldest and most famous industrial factories in Soviet Union and later Ukraine. It is well known due to the famous Kiev cameras. The factory mainly specialized in optical components for the Soviet military and space programs. The factory also produced the professional grade photographic cameras but civil production played only a minor role in factory output.

Sangamo Weston light meter, selenium cell. Measures incident as well as reflected light. I used to drive past the factory on the Great Cambridge Road in the early 1970s; don't expect it's there now as this sort of British industry has withered away unfortunately (unlike the State). Still, we have lots of bankers...

Converted in Perfect Effects 17 using my favorite preset: Ansel Adams. It automatically adds a selenium tone and a vignette as well as a particular array of color channel adjustments.
This is Weston Woods as you have never seen it.
I have sought to get a dreamy feel to this image in photoshop and then adding a gentle amount of the digital equivalent of Selenium toning. This effect ( but much better) used to be achieved in the darkroom in a process called lith printing. I have then framed it digitally.
Metrawatt Leica-METER MC.
Here a drawing of the electrical circuitry.
Not 100% accurate because i should have drawn variable current sources instead of the variable voltage sources but i find that the voltage source symbol makes for easier understanding.
Also the connection of the optional Booster Cell is pictured.
The meters Selenium cell has indeed 1 positive pole and 2 negative poles. So when in dark situations a second part of the Cell can be activated by a switch.

Unfolded Kodak Retina IIIc rangefinder with 50mm Schneider-Kreuznach Xenon f/2 standard lens and original Kodak bayonet mount plastic lens shade. Of course one can no longer fold the lens with the hood on. This is a somewhat fussy camera: one has to return the focus to infinity and press the two buttons on the lens housing in order to fold the lens back into the body. But it's a very neat and well executed construction that still works flawlessly more than 50 years after leaving the factory.
Shot with Alpa 10d and 50mm Kern Macro Switar f/1.8 at f/11, 1 sec on Agfa Vista ISO-200 film. Composite of two frames with Helicon Focus stacking software for increased DOF.
Picked this selenium cell light meter up from eBay for a few quid - with a view to using it with my Mamiya. The cell still seems to work okay, the only problem is I haven't got a clue how to read it... any one any ideas?
Obviously I know to set the ASA of the film in the centre, then the inner ring rotates around - and I guess I have to line something up with the needle... but I don't know what.
UPDATE: I now know the secret! Check out the manual here: www.flickr.com/photos/fwump/3797788562/
(No Photoshop involved. "Traditional" film photography and printing in the dark room)
This is a long exposure (about 12 minutes) using TMax 100 film, a ND filter (8 f/stops down) and a red filter.
This shot was taken with a Mamiya c220, with 55mm lens. Aperture was f/32, to get a maximum depth of field.
I got up early (4:30AM) in the morning to be at the seaside at the appropriate moment (around 7:00AM), when the tide is high and the morning light still delicate.
Development details :
Developed in TMax developer diluted 1+4, 6min15sec at 24°C
Printing details :
Printed on Ilford MGWT FB paper. (shiny surface). Grade used was mostly #5. Developer was Eukobrom.
Toning details :
Toned in a special mixture made of alkaline water, new viradon & selenium to warm the mid-tones to a subtle brown while keeping the shadows dark (thanks to the selenium).
Then wash in a sodium sulfide solution to stop the action of this toner mixture and prevent staining of the paper by the viradon.
Eventually the sky only was slightly toned in a gold toner to add pinkish notes in the highlights (sunrise).

'DRP'
This photograph features an amazing DRP (Direct Reduction Plant) tower at the steel factory. If you ask me, it looks like a rocket launch pad - it's approx 90m tall, insanely complex structure with an absolutely awe inspiring, menacing presence. With all mist, steel beams and hundreds of glowing lights, it also makes one incredibly photogenic subject.
Here's the wikipedia link which explains Direct Reduced Iron, the product of DRP tower. en.wikipedia.org/wiki/Direct_reduced_iron
tech: I took this shot at dawn with Canon 5D Mk2 + Canon TS-E 17mm f4.0L lens and Promote Remote Control for 7-stop HDR bracketing. I used Oloneo PhotoEngine Pro to create a tonemapped image and exported it as 16-bpp TIFF file to Photoshop for futher processing.
I had to create a highly detailed, hand-painted mask to isolate the sky from the DRP tower because I wanted to add a bit of motion blur to the clouds which wasn't present in the RAW file. BW conversion was accomplished with Silver Efex Pro with Blue filter and Selenium toning. Final image with a mix of the original, coloured HDR image + BW image with approx 30/70 blending ratio.
Playing around with Silver Effects 2, thought I'd try another variation of this shot.
Selenium is used to intensify and extend the tonal range of black-and-white images.
The honeycomb structure is a dramatic focal point of the building that responds to several significant design and engineering challenges. The pattern was inspired by the fundamental building block of nanotechnology – the intrinsically stable hexagonal carbon structure of graphene.
Taken during Thursday's UWPC meet.
Another FSU camera and this one has nothing to do with Leica! Very nicely styled and build, this FED Micron is a half-frame camera. It sports a 30/1,9 lens that looks very nice. The viewfinder is bright and clear with frame marks, distance indicator and shutterspeed indicator, all this courtesy of the selenium cell.

Selenium cell still works. Came with leather pouch and case. A bit worse for wear with scratches, glad someone used it so often. It is highly evocative of the pre-war era in its design. A little beauty.
Here's a great website specifically for Weston information. I applaud their dedication to these meters: www.westonmeter.org.uk/Chronology.htm

Sepia & Selenium Toning 2012
I wanted to play in the darkroom last night but didn't feel like setting up the black plastic I use to darken the room. My solution was to play around with some toning, using both Sepia and Selenium toners to get this effect :)
