History re-photographed: This is a project to restore original greyscale images so that they contain a fair representation of the original colour content. A number of algorithms have been developed and some are continually being improved.

James Joule Oil Painting 1863 James Prescott Joule was painted by Geroge Patten in 1863. The painting was destroyed during an air raid on Manchester in 1944. However, a good quality stell plate engraving was made for Jouole's obituary and I have a good print off that. It then becomes a long story to recreate a new 1863 oil painting, which is not George Patten's 150 year old painting, but which in 150 years will have taken its place in science history. The image here shows how things are coming along. There is still some way to go. A 95x70cm oil on canvas will exist by this time next year.
