First job was to clone out the folds, creases and old marks.
I then made a duplicate in black & white then merged over the original at 72% so I could just see what to work on.
Much mapping was done to achieve realistic faded colouring to still achieve an old appearance.
I then needed to optimize the features of both faces and hands and re shade prominent features.
After that I had to re-shadow everything including much in the clothing.
Next was to trim a haze that was evident around all edge then blend to achieve a foreground / background depending on what part I was doing.
Reluctantly I would find it impossible to do commissions as it takes a huge amount of hours to achieve this finish from the original.
