Daguerreotypes are easily identified by a mirror-like, highly polished silver surface and its dually negative/positive appearance when viewed from different angles or in raking light. Daguerreotypes are typically housed in miniature hinged cases made of wood covered with leather, paper, cloth, or mother of pearl.

Are daguerreotype photos valuable?
Record prices in excess of $30,000 have been paid for individual daguerreotypes at auction. At a 1988 Sotheby’s auction, a group of 11 daguerreotypes brought more than $50,000. A common portrait (many are found in hand-tinted color) of an unknown individual in clean condition generally fetches about $30.
How long does a daguerreotype need to expose an image for a photo to be taken?
The image, the result of an eight-hour exposure, was the world’s first photograph. Little more than ten years later, his associate Louis Jacques Mande Daguerre devised a way to permanently reproduce an image, and his picture—a daguerreotype—needed just twenty minutes’ exposure.
How do you make a daguerreotype picture?
How much did a daguerreotype cost?
The price of a daguerreotype, at the height of its popularity in the early 1850’s, ranged from 25 cents for a sixteenth plate (of 1 5/8 inches by 1 3/8 inches) to 50 cents for a low-quality “picture factory” likeness to $2 for a medium-sized portrait at Matthew Brady’s Broadway studio.
What is the difference between ambrotype and daguerreotype?
Ambrotypes were created through a similar process, using glass coated in certain chemicals, then placed into decorative cases. The difference is that while a daguerreotype produced a positive image seen under glass, ambrotypes produced a negative image that became visible when the glass was backed by black material.
Can a daguerreotype be restored?
Daguerreotypes break down with time and can eventually become ruined and unrecognizable. But researchers at Western University in Canada have created a new technique that recovers even the most damaged daguerreotypes. It reveals what lies under the severe degradation and shows the images in all their original detail.
Why are daguerreotypes so clear?
The silver had to be completely free of tarnish or other contamination when it was sensitized, so the daguerreotypist had to perform at least the final portion of the polishing and cleaning operation not too long before use.
What are the advantages of a daguerreotype?
The daguerreotype had two advantages over Talbot’s paper process. First, the daguerreotype was crystal clear, whereas Talbot’s images were not sharply defined because imperfections in the paper negative reduced the quality of the final print.
How long did you have to sit for a daguerreotype?
The exposure time for daguerreotypes was originally anywhere from five minutes to half an hour, making sitting for a portrait a painful and often unsuccessful process. Innovations in the 1840s increased the sensitivity of the photographic plates and reduced the exposure time to under a minute.
How long did you have to sit still for a daguerreotype?
Though early daguerreotype images required an exposure of around twenty minutes, by the early 1840s it had been reduced to about twenty seconds. Even so, photography subjects needed to remain completely still for long periods of time for the image to come out crisp and not blurred by their movement.
What was one of the most significant drawbacks of the daguerreotype photographic process?
What was the most serious drawback of the daguerreotype? Each plate was unique, so there was no way of producing copies.
Can you still make daguerreotype?
To make your own 35mm Daguerreotype will require a short list of ingredients: a small silver or silver-plated copper plate, a 35mm camera, orange or red glass, iodine fuming material and a vessel to hold it, a polishing and buffing block, polishing and buffing abrasives, olive oil, and distilled water.
What do you need for a daguerreotype?
To make a daguerreotype, a sheet of copper is plated with a thin coat of silver. This plate is then cleaned and polished to a mirror finish. Next, it is sensitized in a lighttight box with iodine and bromine vapors until its surface turns yellow.
How do you clean a daguerreotype?
Loose surface dust can be removed with a soft brush or with pressurized air, preferably with air blown from a compressed air can. No other cleaning method can be recommended safely. The unprotected surface of a daguerreotype is sensitive to the slightest touch; such a plate should therefore be handled with utmost care.

Was the daguerreotype process inexpensive?
The daguerreotype process was inexpensive and easy for just about anyone to use. In the early days of photography, cameras were limited to professional photographers because of the knowledge needed to work the cameras and develop the images with various chemicals.
How much did a photograph cost in the 1800s?
The cost ran between 25 cents and 50 cents each plus the 3 cents tax placed to help pay for the was at that time. If you find a stamp for a tax you can now rough figure the date of the photo. That cost would be equal to $3.85 to $7.64 today.
Is tintype same as daguerreotype?
Tintypes, patented in 1856, are actually on iron, not tin. Unlike a daguerreotype, tintypes are not reflective. While you can find them in cases (like the previous two image types), most tintypes found in collections aren’t in any type of protective sleeve or case.
Can daguerreotype be duplicated?
Although daguerreotypes are unique images, they could be copied by redaguerreotyping the original. Copies were also produced by lithography or engraving. Portraits based upon daguerreotypes appeared in popular periodicals and in books.
What are old photos on glass called?
The ambrotype is a photographic process on glass introduced in the early 1850s. The ambrotype quickly grew in popularity because it maintained the image clarity of the daguerreotype—an earlier process on silver-plated copper invented in 1839—but was faster and cheaper to produce.
Can you scan daguerreotypes?
A scanner uses coaxial light – fine for documents, not so good for 3-D and reflective objects. Daguerreotype images are best viewed with oblique light – the image you see is actually a reflection of the light source.
Are daguerreotypes on glass?
How old are they? Daguerreotypes (1840-1855) are on polished silver so they are very reflective, like a mirror. Since they are on silver and subject to tarnish, daguerreotypes were put behind glass and sealed with paper tape so air cannot tarnish the plate (there often is some tarnish around the edges of the picture).
What is a sixth plate daguerreotype?
Sixth-plate daguerreotype. Philadelphia, ca. 1852. The sixth-plate, measuring 2 ¾ by 3 ¼″, was the most popular sized plate for customers since its size made it convenient to slip out of a pocket or purse and hold in one’s hand for easy viewing.
Are daguerreotypes permanent?
The results were not permanent, however; when the developed picture was exposed to light, the unexposed areas of silver darkened until the image was no longer visible.
