Photo

Definition: A photo is an image captured using a camera or similar photographic device. It can be produced digitally or on traditional film or photographic plates, and serves as a representation of a subject, scene, or artwork.

Types of Photos

• Digital Photos: Captured with digital cameras or smartphones, stored as files such as JPEG, PNG, or TIFF.
• Film Photos: Captured on light-sensitive film, then developed chemically to create prints or negatives.
• Glass Plate Photography: An early photographic method using glass plates coated with light-sensitive emulsions.

Applications in Art and Framing

• Used to reproduce or archive artwork for documentation, sales, or exhibition purposes.
• Essential in fine art printing, gallery presentation, and photographic conservation.
• Can be tested for archival stability using procedures like the Photo Activity Test (PAT) to ensure longevity.

Handling and Preservation

• Store photos in acid-free sleeves or archival-quality mounts to prevent degradation.
• Keep away from high humidity, UV light, and fluctuating temperatures to maintain image quality.
• Use non-invasive mounting techniques when framing, such as mounting corners or hinges.
