The Birth of Daguerreotypes: How Early Photography Changed History
Daguerreotypes were introduced in 1839 by French artist and inventor Louis Daguerre. This revolutionary process marked the beginning of commercially available photography.
How do you pronounce daguerreotype? It's said like this: duh-GARE-oh-type.
Before daguerreotypes, capturing an image required either a time intensive procedure with a camera obscura or commissioning an artist to paint a portrait. Daguerre spent years refining his process to create a faster and more precise alternative.
When daguerreotypes became available, they quickly gained popularity all over the world. However, because of their high cost, they were often reserved for the middle and upper classes, cementing their status as luxury items and symbols of wealth and prestige.
The Process of Creating a Daguerreotype
Is a daguerreotype a photograph? Not exactly. Rather, the daguerreotype is a photographic process that imprinted images on a polished metal sheet, usually silver plated copper.
The finished image was incredibly sharp and detailed, but also incredibly fragile.
Here’s How a Daguerreotype Was Made:
- Preparing the Metal Plate:
The process began with polishing a metal plate until it had a mirror-like finish. The plate was then coated with a light-sensitive chemical to capture the image. - Capturing the Image:
Once prepared, the plate was placed inside a camera. Light exposure time varied based on the lighting conditions and the desired result. - Developing the Image:
After exposure, the plate was carefully processed in a chemical bath to fix the image. This involved rinsing the plate with a solution of saltwater and alcohol, followed by exposure to mercury vapor. The mercury reacted with the light-sensitive coating, revealing the image. - Polishing and Protecting:
The final step was a second polishing, which enhanced the plate’s reflective, mirror-like finish. The completed daguerreotype was placed in a protective case to shield it from dust, scratches, and fingerprints.
Creating a daguerreotype required a lot of skill and precision. The exposure time had to be carefully managed to avoid underexposing or overexposing the image. Despite these challenges, the result was a one-of-a-kind photograph with unmatched clarity and detail.
How to Identify an Authentic Daguerreotype
If you’re wondering whether your picture is a daguerreotype, there are a few distinct features to check. Here’s how you can tell:
Does it have a mirror-like finish?
The polished silver surface of a daguerreotype creates a mirror-like reflection that distinguishes it from other early photographs. Try holding the image at different angles in the light. If it reflects like a mirror, you likely have a daguerreotype.
Does it have a high degree of detail?
Daguerreotypes were renowned for their sharpness and fine details, especially in portrait photography. If your image shows crisp, intricate details, it could be an original daguerreotype.
Is it in a protective case?
Since daguerreotypes are fragile, they were usually sold in cases designed to protect them from damage like scratches and dust. These cases were often made of leather and lined with velvet or silk. If your picture is stored in an ornate case with a lining, it’s another clue that you’re holding a daguerreotype. The original protective cases for daguerreotypes were often lost or damaged over time. Therefore, if your daguerreotype is uncased, it doesn’t necessarily mean it’s not authentic.
Daguerreotype Plate Sizes
The size of a daguerreotype can significantly affect its value. Larger plates are generally more valuable because they provide a more immersive viewing experience and showcase greater detail.
According to American Antiquarian Society, the most commonly produced daguerreotype plate sizes include:
- Sixteenth Plate - 1 ½" x 1 ¾"
- Ninth Plate - 2"x 2 ½"
- Sixth Plate - 2 ¾" x 3 ¼"
- Quarter Plate - 3 ¼" x 4 ¼"
- Half Plate - 4 ¼" x 5 ½ "
- Whole Plate - 6 ½" x 8 ½"
- Mammoth Plate - Larger than 6 ½" x 8 ½"
Collectors look for larger plates not only for their impressive display but also for their rarity. A whole-plate daguerreotype, for example, can sell for much more than a smaller ninth-plate version of the same subject due to its size and detail.
Understanding plate sizes can help you estimate your daguerreotype’s worth and provide key insights for potential buyers and collectors.
What Determines the Value of Antique Daguerreotypes?
Some daguerreotypes are highly valued by collectors and remain a popular focus at antique photography auctions. However, not every daguerreotype is valuable. Several key factors—such as age, condition, rarity, and subject matter—determine whether a daguerreotype will command a high price.
Pro Tip: Just because a picture is a daguerreotype doesn't automatically mean it is valuable.
Unique, One-of-a Kind Pictures
Each daguerreotype is a one-of-a-kind creation. Unlike later forms of photography, they could not be reproduced from negatives. This rarity is part of their appeal—there is truly only one version of each image.
Condition Really Matters
The condition of a daguerreotype plays a big role in its value. Well-preserved images fetch higher prices, while damaged or tarnished plates often sell for much less. Since daguerreotypes are delicate, many show signs of wear, which can impact their worth.
Subject Matter and Historical Significance
The subject of the image is another crucial factor. Daguerreotypes featuring historical events, notable individuals, or iconic locations often sell for far more than everyday portraits. Images with documented provenance, such as a known history of ownership, also hold added value.
Exceptionally rare and incredible daguerreotypes have sold at auction for as much as a whopping $95,600. Wondering what in the world THAT picture was? It was a half-plate size depicting a traveling photographer's mobile studio, sold at Heritage Auctions in 2010.
Common Daguerreotype Subjects
Most common daguerreotypes feature family portraits—men, women, children, and couples were popular subjects. Unidentified portraits are readily available on the market and often sell for less than $50. Images of homes, soldiers, and post-mortem portraits (depicting the dearly departed) are rarer and can range from $5 to $5,000 or more, depending on condition and provenance.

Daguerreotype Cases: Protecting History and Adding Value
The protective case is often just as significant as the daguerreotype itself. Collectors sometimes seek out cases even without the images inside, as they hold historical value and can contribute to the overall worth of a daguerreotype.
The Union Case
One of the most popular types of cases is the Union case, introduced in 1854. These cases became especially popular during the 1850s and 1860s, particularly during the Civil War. Despite the name, "Union" wasn’t a reference to political unity but rather a branding choice. Many manufacturers added "Union" to their product names to evoke feelings of patriotism and unity.
If you pick up a Union case, you might initially assume it is made of leather or wood. Actually, the material used in daguerreotype Union cases is a form of something called thermoplastic. Thermoplastic is a durable material created by combining shellac, wood flour, and other substances. The material was softened with heat and molded into intricate patterns that often resembled carved wood or embossed metal. These details made Union cases not only protective but also decorative.
Antique daguerreotype Union cases can range in value from to $5 - $2,000. One of the rarest Union case designs shows an eagle standing atop a globe; an example of this design sold at auction for $2,500 in 2018.
How to Care for Antique Daguerreotypes
Proper care is needed to preserve a daguerreotype’s condition and value. Store your daguerreotype in a safe, dry place away from direct sunlight, moisture, and pollutants such as smoke.
While many daguerreotypes originally came in original protective cases, some are found loose or in homemade envelopes. The case was meant to forever seal the delicate image inside. Without a case to protect it, over time, exposure to the elements can cause the daguerreotype picture to tarnish, fade, or even disintegrate, rendering it worthless. If your daguerreotype is uncased, consider placing it in a custom protective enclosure.
When cleaning the surface, use a soft, dry cloth to gently remove dust and dirt. Avoid using liquids, as moisture can damage the image. Always handle daguerreotypes with gloves to prevent fingerprints and oil from transferring onto the surface, as these marks can lead to long-term damage.
Following these steps will help maintain the historical integrity of your daguerreotype and preserve its value for years to come.
The Enduring Legacy of Daguerreotypes: A Milestone in Photography
