He exposed a silver-plated copper sheet to iodine vapor, creating a layer of light-sensitive silver iodide ; exposed it in the camera for a few minutes; developed the resulting invisible latent image to visibility with mercury fumes; then bathed the plate in a hot salt solution to remove the remaining silver iodide, making the results light-fast. He named this first practical process for making photographs with a camera the daguerreotype , after himself. Its existence was announced to the world on 7 January but working details were not made public until 19 August. Other inventors soon made improvements which reduced the required exposure time from a few minutes to a few seconds, making portrait photography truly practical and widely popular. The daguerreotype had shortcomings, notably the fragility of the mirror-like image surface and the particular viewing conditions required to see the image properly. Each was a unique opaque positive that could only be duplicated by copying it with a camera.

Mammoth drawings are not unusual in such cave art, but the depiction of an apparent theropod dinosaur is remarkable. In BC, under the reign of King Nebuchadnezzar, a Babylonian artist was commissioned to shape reliefs of animals on the structures associated with the Ishtar Gate.
Many centuries later German archaeologist Robert Koldewey stumbled upon the blue-glazed brick and that gate was rediscovered in The animals appear in alternating rows with lions, fierce bulls rimi or reems in Chaldean , and curious long-necked dragons sirrush. The lions and bulls would have been present at that time in the Middle East. But, on what creature did the ancient Babylonians model the dragon?
The same word, sirrush, is mentioned in the book of Bel and the Dragon, from the Apocrypha. Both the description there and the image on these unearthed walls, which are now displayed in the Berlin Vorderasiatisches Museum, appear to fit a sauropod dinosaur.

Example of cabinet card with photographer’s details – this photog’ was at this address Like me, you may have a collection of old photographs handed down to you with no knowledge of who the portraits are of, or even when they were taken.

Technical details[ edit ] There are two historic tintype processes: In the wet process, a collodion emulsion containing suspended silver halide crystals had to be formed on the plate just before it was exposed in the camera while still wet. Chemical treatment then reduced the crystals to microscopic particles of metallic silver in proportion to the intensity and duration of their exposure to light, resulting in a visible image. The later and more convenient dry process was similar but used a gelatin emulsion which could be applied to the plate long before use and exposed in the camera dry.
In both processes, a very underexposed negative image was produced in the emulsion. Its densest areas, corresponding to the lightest parts of the subject, appeared gray by reflected light. The areas with the least amount of silver, corresponding to the darkest areas of the subject, were essentially transparent and appeared black when seen against the dark background provided by the lacquer.
The image as a whole therefore appeared to be a dull-toned positive. To obtain as light-toned an image as possible, potassium cyanide , a very dangerous and powerful deadly poison, was normally employed as the photographic fixer. It was perhaps the most acutely hazardous of all the several highly toxic chemicals originally used in this and many other early photographic processes.

History[ edit ] A photograph of a wedding party probably from the late s to s. Note the black or dark-colored wedding dress, which was common during the early to mid th century. The carte de visite was displaced by the larger cabinet card in the s. In the early s, both types of photographs were essentially the same in process and design. However, later into its popularity, other types of papers began to replace the albumen process.
Despite the similarity, the cabinet card format was initially used for landscape views before it was adopted for portraiture. Some cabinet card images from the s have the appearance of a black-and-white photograph in contrast to the distinctive sepia toning notable in the albumen print process. These photographs have a neutral image tone and were most likely produced on a matte collodion , gelatin or gelatin bromide paper.
Sometimes images from this period can be identified by a greenish cast. Gelatin papers were introduced in the s and started gaining acceptance in the s and s as the gelatin bromide papers became popular. Matte collodion was used in the same period. A true black-and-white image on a cabinet card is likely to have been produced in the s or after The last cabinet cards were produced in the s, even as late as
The Ghosts of Old London December 26, by the gentle author Click to enlarge this photograph To dispel my disappointment that I cannot rent that Room to Let in Old Aldgate , I find myself returning to scrutinize the collection of pictures taken by the Society for Photographing the Relics of Old London held in the archive at the Bishopsgate Institute. It gives me great pleasure to look closely and see the loaves of bread in the window and read the playbills on the wall in this photograph of a shop in Macclesfield St in The slow exposures of these photographs included fine detail of inanimate objects, just as they also tended to exclude people who were at work and on the move but, in spite of this, the more I examine these pictures the more inhabited they become.

I’ve been to the Appalachians in the last decade and you can still see places and people that look and live like this. Our family wasn’t considered poor but I remember as a child bathing in tubs and hanging laundry out to dry even in the snow. As a very young child we were poor and lived in a place called Mulligan Flats near what is now downtown Oklahoma City. It has since been condemned and paved over but even the ramshackle hovels were whitewashed, the yards were kept picked up and mowed, people’s home interiors were kept clean and guests were always served something to eat on your best dishes.
People were horrified and greatly insulted to be offered “charity”. Willingness to work was considered one of the greatest virtues and unwillingness to work was worse than drunkenness. We were not allowed to wear jeans in public; mini skirts would elicit a beating from grandma, gloves and hats were considered essential wear for any public function and only “white trash” would allow themselves to be seen in public without such accouterments.
Grandma would say, “You may have to be poor but you don’t have to be dirty or ignorant so go take your bath and do your homework! Now, we call “poor” those that don’t have a tv in every room.
