 I took the first overview of the photographs to look what is here, what can I maybe find out or what will come for the next weeks or you never know it before. That's the important thing to look on original artworks and then I saw things I never expected. Robert Tumble McPherson was a Scottish photographer. In an obituary in the newspaper The Scotsman he was called the father of photography of the eternal city and that means something to name someone like this. Robert McPherson started as a support painter and he was moving to Rome in 1840 and working still as a painter until 1845. Then he worked as an art dealer. How to understand the technique Robert McPherson used when he took his photographs? It is important to be in Rome, look on the places, look which point of views did he use. Can I see or can I find the point of view he used? Today it is more difficult to find this because it is 170 years later. But that's the thing when you are standing there then you can look when you take a picture today up. It isn't possible from this point of view so he must be standing somewhere else. So it is important to go on the side, to look there, to be there, to try to think how Robert McPherson did his picture, to come in his mind. And that's also the reason why I'll use for this an old, old large camera. The reason why I'm here in the British School of Rome is that they have here in the archive one of the best collections of photographs of Robert McPherson. I found that there are pencil traces, marks of some clamps and so the most astonishing thing was that I found a fingerprint of Robert McPherson. When you enlarge this part of the photograph you can see that it's not only in the print. The fingerprint is on the glass negative and was printed then on the print and now you can see it very clearly. So that's important to look at originally.
