This technical report describes a photograph in ideal conditions: free of residual chemicals, sealed in stainless steel in an inert atmosphere at 50 percent relative humidity and 50 degrees Fahrenheit. This protects against gas and particulate pollutants, volatiles, fungus and insects. Stress good processing for contemporary photographic materials. Residual chemicals in photographs should be refixed, rewashed and treated with a wash accelerator and hypo eliminator. Identify and remove nitrocellulose film. Inspect nitrate film frequently. Photographs can be copied using appropriate film and filter. Kodak Professional Direct Duplicating Film SO-015 is recommended. Instructions for cleaning daguerreotypes, collodion wet plates, tintypes and ambrotypes are given. Chemical intensification can improve some prints and negatives. All substances in contact with photographic materials should be acid-free. Transparent sleeves made from Kodacel, a cellulose triacetate sheet are suggested. Store in vented containers of anodized aluminum or stainless steel. Place glass plates on edge. Metal frames and plexiglass can be used for display. Cut Permalife paper corners for mounting. Avoid dry mounting. Recipes for fungicides, developer, fix, hypo eliminator, toners, stain, scale and plating removers are given. -- CCI
