About Bob Todrick Expertise I can answer questions on most areas of photography. Though fine-art nudes is my main focus, I can, as well answer most questions dealing with darkroom processes (including many alternative processes).
My expertise does not include digital.
Experience I have photographed since 1975. Among my clients have been a number of major retail department stores (the Bay, Eatons). I photographed for Canada's premier motorsports magazine for a number of years, and have done much portraiture and wedding photography.
In 1990 I gave up shooting professionally to concentrate on my fine-art work and have had numerous group and one person shows since.
Organizations Co-founder of the Group of Several.
Publications Numerous newspaper and print ads.
GRAPHIS photo annual.
Question how long does it take for 35 milimiter negatives of 4x6 photos to fade?
when pix fade do they do so totally?
and become totally balnk?
will theylook like film that was not shot but developed anyways (despite that there was no picture on the film frame)?
how does a very faded negative look like?
is it blank?
how is it different than a picture that was not taken but submitted for processing anyways?
Answer Firstly, black and white negs, properly processed last literally hundreds of years. There are still surviving negs taken in the middle of the nineteenth century that are still printable. Same for black and white prints.
Color neg film will usually last a minimum of 15 to 20 years before there will be any noticeable fading...and even then it will be slight. Most current color negs are considered archival to about 75 years (meaning they will be easily printable by a competent darkroom tech.
Color slides fall into two categories, E6 process and kodachrome. E6 (Ektachrome/Fujichrome) have the same life expectancy of the above color neg materials.
Kodachrome, properly stored is thought to last a minimum of 200 years (Kodachrome was invented in the 1930's so this is of course an estimate).
Properly processed and STORED (meaning not subject to direct harsh light and in specific temperature and humidity ranges) no negatives have ever completely faded to 'nothing'. If you have seen negs that have done so they were either improperly processed or stored.
