In a new article posted on his "icons Workshop" André Gunthert talk of the photograph of Aden. I note in his article this:

[...] I am not convinced by the comparisons featuring portraits of the bearded figure identified as George Révoil, and is the most obvious resemblance Dutra. We must thank Jacques Welcome to the new progress in studying the document.

What seems to refute a recent article on this issue.

I remember Mr. Gunthert was mistaken about the date of onset of gelatin bromide. It was originally written :

Especially, two years after the find, the document has now been sold to a collector has not undergone an evaluation by a specialist photographic history. What can smile, knowing that the time range given by the discoverers to date the picture is the period 1880-1890. This decade is precisely cut in two by the introduction of new technology, the gelatin silver bromide dry plate or, simply identify the method to locate the shot before or after 1885, and thus close to half the range.

What led him to date the photograph in the year 1885. Now in his thesis, he recently released, it says at page 231 : "From in 1879 the process Gelatin silver bromide knows a rapid expansion of its distribution in France [...]". And he says it with amateur photographers and professionals alike.

And then, I confess I do not understand any of this mistake. Mystery.

Finally, the lack of expertise of the photo, we can not say with certainty about the fact that the photographic process is the famous gelatin bromide. I tend to caution the statements of Mr. Gunthert.

For a refutation of the theses of Mr. Gunthert see my article:
