Which is the preferred salvage method for all photographic materials?

Which is the preferred salvage method for all photographic materials? Correct Answer Air drying

Explanation:

  • Photographs are composite, laminate structures composed of supports, binders, and image material.
  • Binders, when present and image materials combined are referred to as the image layer.
  • Common supports are paper, plastic, glass, and metal.
  • Common binders are gelatin, egg white (albumen), collodion (cellulose nitrate), gums, and starches.
  • Common image materials are silver and other metals (iron, platinum, palladium, etc.), organic dyes, pigments, and inks.

Salvage Techniques

Drying

  • Slow, air drying is the preferred method for the recovery of photographic materials. Set up fans and/or dehumidifiers to keep the air moving and dry.
  • Line Drying: Set up a clothesline and hang materials to dry with clothespins or paperclips, which can be inserted in the rope to prevent sliding toward the middle. Paper clips make effective, inexpensive "S-shaped" hooks to hang film negatives with sprocket holes.
  • Flat Drying: Several tiers for drying can be created by using stiff flat support such as corrugated board or fiberglass window screens that is supported on disposable cups or other similar-sized objects between each tier. Place Photographs and negatives face up (dull or image side) on an absorbent surface such as blotter or on a screen. Do not touch the surface or blot off excess water.
  • Air dry vertically, plastic film negatives, glass, ceramic, or metal-based photographs.
  • Open cased photographs and photographic albums to slowly air dry.
  • Open albums to slowly air dry. Sturdy albums can be placed upright, like a book, fanning out the pages for air access. Albums that cannot be placed upright can be opened flat with spacers (e.g. wadded paper, paper towels, waxed-freezer paper), inserted to allow air circulation between pages. Take care to avoid placing bundled material across photographic surfaces in double-sided mounted photographic albums. Reduce the likelihood of double-sided album pages sticking by inserting waxed or freezer paper between pages before freezing.
  • If photographs are wet within their frame, unframe carefully watching for any areas that may be stuck to glass or mats and air dry. Don’t hang photographs in wooden frames to dry. Joints may be loosened from moisture.
