Claudia, it's a strange reference but what you said reminded me my old job. I used to re-touch old photographs of people's loved ones (always dead people for some reason). For this, I used to meet the client to collect as many photographs as possible to produce a realistic image. One day a client met me with no photographs and started to describe how his father looked like before he died. When I realised that he thought I could produce an image with no pictures and told him this was not possible, he started to shout at me saying things like "what kind of an artist are you, I came all the way to get a photograph, you are a fraud blah blah..."
