How to Restore Tintype Photos
Tintypes are a very early type of antique photograph dating back to the late 19th century. They were originally created by coating specially made tin plates with a light sensitive emulsion. These light sensitive plates were placed in holders in the back of view cameras and exposed to light when the photographer opened the camera lens. The plates were then processed in a darkroom with chemicals. The resulting portraits were gray in appearance with good detail but generally flat in contrast. There is no negative in the tintype process, making each one a rare, one-of-a-kind photograph. Tintypes are valuable capsules of history and should only be directly worked on by an archival specialist. Today virtually all tintype images needing restoration are restored digitally on the computer.

Study the condition of tintype to determine if it needs to be cleaned. If there are small pieces of emulsion or rust flaking off, do not clean it. If the surface is stable but in need of cleaning, gently clean it with a cotton swab and distilled water. Blow dry with hair dryer.

These tools will include paint brushes, cloning tools and contrast and saturation controls. Some computer photo programs allow working in layers, so that the original image file is not disturbed. This allows for going back over the steps made in the restoration to make changes.

Tips & Warnings
When using a scanner to copy a tintype, place the tintype in a clear plastic sleeve before placing it in the scanner bed to prevent scratching the top glass of the scanner.
During computer restoration, keep tintype close at hand so that you can refer to it, Use a magnifier to study the area being worked on. Be sure to protect tintype while handling by keeping it in an archival polyethylene plastic sleeve.
Like all black and white processed photographs, keep tintypes out of direct sunlight, to prevent fading. Store in dark, dry place.
Be careful when handling tintypes. They often have sharp edges and corners because of being cut with tin snips.
Do not touch the surface of tintypes with your bare fingers because grease in your skin will transfer onto the surface and can damage the image or emulsion.
