Sometimes, looking at a photo straight on, will not reveal any damage, as you can see with this image. Looks fine, doesn’t it?
Not so when you start tilting it slowly in the reflection of light. Suddenly we had to discover severe scratches, mainly on the face. It is impossible to determine how they have been caused. One can only speculate that the photo had at some stage been stored together with an object that has sharp edges. Maybe it was in an envelope, together with such an object.
The photo hasn’t faded and other than a slight crease in the top right corner and those nasty scratches there is nothing more to do.
This is the fixed image, and its new print is now safely stored away in an album.
