Small Bewi Piccolo selenium light meter. The dimpled on the front are the light receptors. This is the smallest meter I have ever seen
The Selenium element was known to science in the late 1800s as having the property of outputting a voltage when exposed to light, but the amout of output was so small and fleeting in its output characteristics that it made it little more than wondrous novelty to early electricity scientists and their backers of the day. Then somewhere around the late 1920s, Weston figured out how to meld this element with other others to stabilized this earliest of solar cells and make their output large enough to drive one of their most efficient meter movements of the era like the Weston 301 movement which is used on this early generation foot-candle meter modeled 614 and set out out to make a device that could be used to reliably and repeatably measure all manner of light sources and provided a handy guide for establishing lighting standards for home, work and industry. Weston originally thought about using it for automatically triggering street lighting to come on when it got dark and turn back off once the sun rose bright enough to trigger the off switch. It also got adapted into elevators to stop the doors from closing when a person broke the beam to switch the door back open. Relays, were also a going concern in Weston's affairs and they excelled in all of these various studies in electricity.
There were a handful of these models made from very compact to more industrial sized models aimed strictly at industry users. The whole craze of photography also leaped on board with this as well, as Weston helped to establish a means of scientifically setting up your camera settings based on the light in the shot. Film makers of the day as well took hold of all this new technology Weston brought to the playing field and Weston made specific meters for them as well.

From a study of the pollutants in the Los Angeles River. Each Page documents the 43 pollutants in the river. Each pollutant has its entire life cycle described, plus how we might phytoremediate and mechanically remediate the pollutant. Also included with the cultural information is the scientific signatures of each compound-how we discover them in the water.

I was imagining what you'd see if an early 19th century press photographer got taken back in time to the dinosaurs (except of course dinosaurs would have had skin)

I found this on local bike trail.
The irony was striking. I printed this when I first learned to lith print so needless to say if wasn't as good as I wanted. I recently came back to it and I am really pleased with it now.

This shot was taken in Pascoag, RI for my "Best Camera Project" using an Olympus E-600.
A very intense, fast moving thunderstorm raced by around 2:30 this morning. Flashes of lightning were near constant, but since the thunderhead was pretty large, few of the bright flashes had visible bolts... come to think of it, there were only a couple of thunder reports that were even nearby. This is actually the only catch I made out of about a hundred shots.

Sometimes I feel like I nut. I rarely don't. It's tough to pick a favorite when the competition includes cashews, almonds, pistachios, peanuts (not really a nut, yeah yeah), and macadamias. But I think I go for the gorgeous Brazil nut, with its pitted, finished-hardwood skin and porcelain white meat.
From Twelve Things You Should Know About Selenium":
"9. A nut a day keeps the blues away. The Brazil nut is the richest of all foods in selenium, and eating a single nut a day will guarantee you are never deficient, says Dr. Donald J. Lisk, director of Cornell University’s Toxic Chemical laboratory. He found that Brazil nuts are grown in selenium-rich soil providing a super high content of the mineral, about 2,500 times more than other nuts. Eating half a dozen nuts rapidly boosts blood selenium levels by 100350 per cent. The taking of selenium in supplementary form is both expensive and unnecessary provided the foods listed are eaten on a regular basis."
And there are some good reasons to boost your selenium.
Selenium colour effect to enhance the moonlit effect. The other photo uploaded has no alteration to colour and the 5 minute exposure in moonlight makes it look as though it is daytime-view it to compare to this one.
This image has had no colour adjustments and the light from the moon and the security light from the Manse was enough to illuminate the church in the full spectrum of wavelengths of light and thus give it afull colour 'daytime-like' appearance. I felt this was not atmospheric enough and redone this image in a selenium tone to ehance the moonlit mood. See accompanying image for comparison.
Crichton Church was founded on 26 December 1449 by William Crichton, 1st Lord Crichton, Lord Chancellor of Scotland "Out of thankfullness and gratitude to Almighty God, our Lord Jesus Christ, the Blessed Virgin Mary, St. Kentigern and All Saints", with the consent of his son, James of Frendraucht and confirmed on the 29 December by James Kennedy, Bishop of St Andrews. Like many other collegiate churches, Crichton was built for the use of the local lord, and a provost, eight prebendaries, two choir boys and a sacrist were appointed to pray for the souls of the Crichton family. The provost was granted the tiends and tithes of the prebends, the Rectory of Crichton and the Temple lands appertaining to Crichton.
The church was built in a Gothic and Romanesque cruciform style with a large central tower; the nave was used as the place of worship for the poor people. This continued until the Scottish Reformation of 1560 when it was considered unusable.
By 1569 it was being used as the parish kirk (church) and a minister, Adam Johnston, was ordained to lead the service. By the 1580s, major restoration work began, though the nave was said to be ruinous, as it is to this day. In 1641, by an Act of Parliament, Crichton Church was declared to be the parish church for all time. Though there was more restoration and adaptation in 1729 it was considered to have been carried out "badly". More work in the 1820s helped to bring the old church back to life, but it was not until the end of the 19th century that the church was fully restored, by the Edinburgh architects Hardy & Wright. Stained glass windows were installed at this time

43 years after ...
Damaia, near Lisbon, 1972, in one of the first "bidonville" created to accommodate the Cape Verdean emigrants who came to work in Portugal.
The original printing, ultra contrast and Selenium toning was lost "in the time vortex".
This one was digitally re-created , from the negative (Kodak TRI-X exposed to ISO 3200).

Obsolete today, selenium rectifiers were commonly used in military and civilian electronic equipment during the service life of the Nike Hercules system. While they were more reliable than vacuum tube rectifiers, this warning is a testament to the hazards they could pose when they did fail.

With invercone for incident light measurements. Selenium meter with two ranges, the low range is set by opening a perforated window over the cell, which allows more light onto the cell and shifts the display scale to a lower range.
General Electric DW-68 selenium cell exposure meter, probably dating from the 1950s - 1960s.
These old selenium cell meters last forever. This one works perfectly.
This style meter reminds me of the hand-held phaser weapons from the original Star Trek television series.
Selenium quadtone custom version... mmmm... I love the duotones. PS is still usefull. ;-) Not just ACR.

Selenium-toned silver print
From the series Conanicut Island
We were driving over the Longfellow Bridge in Cambridge when she noticed the small boats moving in unison on the Charles River, and she said, “They are doing their ballet”. When I came around the east side of Beavertail on this Sunday afternoon, I noticed many small boats performing their ballet. I also noticed the sky and water were a seamless, deep-blue tone.
By the time the camera was set up, the small boats were gone and larger boats were arranged as you see in the print. In his books, Ansel Adams cautioned against the use of empty black areas in an image. This warning was the inspiration for a time I call the “black period”.
Take advantage of what is there, by making use of what is not.
