A Brief History of Photography

Understanding the evolution of photographic technology is essential for accurate identification and dating of antique photographs. Each era brought new innovations that left distinctive characteristics on the images produced.

The Dawn of Photography (1839-1860)

The invention of photography was announced simultaneously in France and England in 1839. Louis-Jacques-Mandé Daguerre revealed the daguerreotype process, while William Henry Fox Talbot presented the calotype. These revolutionary inventions forever changed how we capture and preserve memories.

• 1839: Daguerreotype process publicly announced in France
• 1841: Talbot patents the calotype paper negative process
• 1851: Frederick Scott Archer introduces the wet collodion process
• 1854: André-Adolphe-Eugène Disdéri patents the carte de visite format
• 1856: Tintype (ferrotype) process patented in the United States

The Golden Age of Studio Photography (1860-1900)

This period saw photography become accessible to the middle class, with portrait studios opening in every town. Standardized formats like cabinet cards made photographs affordable keepsakes.

• 1866: Cabinet card format introduced
• 1871: Gelatin dry plate process developed
• 1880s: Snapshot photography begins with hand-held cameras
• 1888: Kodak introduces the first consumer camera
• 1895: Snapshot photographs become widely popular

The Transition to Modern Photography (1900-1940)

The early 20th century brought mass-market photography and new formats that would eventually lead to the modern photographic era.

• 1900: Kodak Brownie camera democratizes photography
• 1907: Autochrome color process introduced
• 1920s: Real photo postcards peak in popularity
• 1935: Kodachrome color film introduced
• 1936: First 35mm SLR cameras appear

Daguerreotypes: The First Photographs

Daguerreotypes represent the first commercially successful photographic process and remain highly prized by collectors. Understanding their unique characteristics is essential for proper identification.

Identifying Characteristics

Daguerreotypes possess distinctive features that set them apart from all other photographic processes:

• Mirror-like surface: The image appears on a highly polished silver-plated copper sheet with an unmistakable reflective quality
• Angle-dependent viewing: The image shifts from positive to negative depending on the viewing angle and lighting
• Lateral reversal: Most daguerreotypes show the image in reverse (mirror image) unless a reversing prism was used
• Delicate surface: The image sits on top of the plate and can be easily damaged by touching
• Brass mat and preserver: Images are typically sealed under glass with a brass mat (often gilded)
• Protective case: Most daguerreotypes are housed in hinged leather or thermoplastic Union cases

Dating Daguerreotypes

Several factors help establish when a daguerreotype was made:

• 1839-1841: Very early examples are rare; images often have a bluish or cool tone
• 1842-1847: Improved techniques produce warmer tones; hand-coloring becomes common
• 1848-1855: Peak production period; gilt brass mats become standard
• 1856-1860: Declining use as ambrotypes and tintypes gain popularity
• Post-1860: Daguerreotypes are rarely made after this date in the United States

Size Classifications

Daguerreotypes were made in standardized sizes that help with dating and valuation:

• Whole plate: 6½ × 8½ inches (extremely rare and valuable)
• Half plate: 4¼ × 5½ inches (rare)
• Quarter plate: 3¼ × 4¼ inches (common)
• Sixth plate: 2¾ × 3¼ inches (most common)
• Ninth plate: 2 × 2½ inches (common)
• Sixteenth plate: 1⅜ × 1⅝ inches (jewelry pieces)

Notable Makers and Studios

Some daguerreotypists achieved fame and their work commands premium prices:

• Mathew Brady: Famous for Civil War photography; earlier daguerreotype work highly valued
• Southworth & Hawes: Boston partnership known for exceptional artistic quality
• Jeremiah Gurney: New York City daguerreotypist with distinctive style
• Robert Cornelius: Philadelphia pioneer who made one of the first self-portraits
• Antoine Claudet: London-based daguerreotypist with royal patronage

Ambrotypes: Glass Plate Portraits

Ambrotypes bridged the gap between expensive daguerreotypes and economical tintypes, offering a glass-based alternative that was cheaper to produce while maintaining excellent image quality.

Identifying Characteristics

Ambrotypes have distinctive features that distinguish them from other photographic processes:

• Glass substrate: The image is created on a glass plate coated with collodion
• Dark backing required: The image only appears as a positive when backed with black material (velvet, paint, or paper)
• Consistent viewing: Unlike daguerreotypes, the image doesn't shift with viewing angle
• Non-reflective surface: Glass surface doesn't have the mirror-like quality of daguerreotypes
• Hand coloring: Many ambrotypes feature hand-applied color, especially for cheeks and jewelry
• Similar presentation: Typically housed in the same cases as daguerreotypes

Types of Ambrotypes

Several variations of the ambrotype process exist:

• Collodion positive: Standard ambrotype on clear glass with dark backing
• Ruby ambrotype: Made on red or ruby-colored glass, producing rich tones
• Double-sided ambrotype: Two glass plates sandwiched together with backing between
• Cut-down daguerreotype: Some ambrotypes were made from reused daguerreotype plates

Dating Ambrotypes

Ambrotypes were produced during a relatively brief period:

• 1854-1856: Introduction and early adoption; often experimental quality
• 1857-1860: Peak popularity; highest quality examples
• 1861-1865: Civil War era; many soldier portraits
• Post-1865: Largely replaced by tintypes and paper photographs

Condition Issues Specific to Ambrotypes

Ambrotypes face unique preservation challenges:

• Lifting emulsion: The collodion layer can separate from the glass
• Glass breakage: Cracked or broken glass is common
• Backing deterioration: Black backing material may fade or peel
• Silvering damage: Edge deterioration similar to old mirrors

Tintypes: Photography for the Masses

Tintypes (also called ferrotypes or melainotypes) democratized portrait photography, making images affordable for working-class families and Civil War soldiers alike. Their durability has allowed many examples to survive to the present day.

Identifying Characteristics

Tintypes have unique features that make identification straightforward:

• Metal substrate: Image created on thin iron sheets coated with black or brown lacquer
• Magnetic: Tintypes will attract a magnet (this is the quickest identification test)
• Dark background: No backing required as the metal itself provides the dark background
• Relatively flat tones: Less contrast and detail than daguerreotypes or ambrotypes
• Often hand-colored: Tinting for cheeks, lips, jewelry, and clothing was common
• Variable quality: Ranges from carefully composed studio portraits to quick carnival shots

Types and Formats

Tintypes were produced in various sizes and presentations:

• Cased tintypes: Presented in same Union cases as daguerreotypes and ambrotypes
• Paper sleeve tintypes: Mounted in simple paper envelopes or folders
• Gem tintypes: Tiny (1 × 1 inch) images, often used in jewelry or albums
• Bon-ton tintypes: Oval or shaped tintypes with decorative borders
• Outdoor tintypes: Taken by traveling photographers at fairs and carnivals
• Carte-sized tintypes: Made to fit standard carte de visite albums

Tintypes span a long production period with distinct phases:

• 1856-1860: Early period; often presented in Union cases; higher quality
• 1861-1865: Civil War era; many soldier portraits; patriotic themes
• 1866-1880: Peak production; diverse formats and sizes
• 1880-1900: Declining quality; often casual carnival or fair photographs
• 1900-1950: Limited novelty use; boardwalk and amusement park tintypes

Civil War Tintypes

Civil War-era tintypes are among the most collected and valuable:

• Soldier portraits: Young men in uniform, often with weapons
• Patriotic cases: Union cases with flags, eagles, or political themes
• Identified subjects: Images with names or unit information command premiums
• Confederate subjects: Much rarer and more valuable than Union subjects
• African American soldiers: Extremely rare and historically significant

Paper Photographs: CDVs and Cabinet Cards
