When I retired, photography was one of the new interests I wanted to explore. My retirement present was photographic equipment and a City and Guilds course 923, "An introduction to black and white photography was commenced.
One of the most difficult skills attempted was "Restoration of old photographs" without the use of a computer or airbrush.
I found an old "carte de visite" size photo of a lady in 1880s dress. It was obvious that an inkblot had landed on her waist and the surface had been rubbed away as someone had tried to remove the stain.
We used a 5x4 monorail combo camera. After experiments an 8x6 print was produced, but a Kenro "spot-on" bottle kit and "spot-off" had to be purchased to complete the artwork. The result was then rephotographed to produce the original size print and sepia toned to copy photos of that period.
Three months later my aged aunt came over from USA and stayed with us. As soon as I showed her the photograph she said, "Thats my Mother; but she never had a figure like that!" I had used the exercise to give her the figure I thought she should have.
During that conversation I learned that she had owned a dress and corset shop, being a trained dressmaker, before she married.
Next day I took her to the museum of English costume in Platts Fields. I had rung the curator that we were coming and that my auntie was a primary source of information about dress in the Edwardian period.
At one point in their conversation my effort to restore the old photograph was mentioned and, to my surprise, they agreed that I had only followed in the footsteps of photographers of that period. They too enhanced the figures of their lady sitters, as a matter of course.
