The art world may or may not coincide with the way successful artists think or with what they believe. The art world is primarily marketing but artists themselves are usually about creating - they channel a drive that brings art into being. But that it's even called "art" is sometimes more the result of marketing than anything the artist believes or says. Ontologically, it's a mess.
Which gives me a cynical eye to what's presented. I don't know the vast majority of well known artists. I generally have to look them up to get familiar with their work. Many times I have an ignorance of the era or reason for their work. Other times it just doesn't speak to me at all. No idea why or what the person is saying and for what reason. Other times the work straight out of the gate is impressive and then there are times it takes some studying to figure it out.
A lot of work that I see that people go gaga over seems to lack anything that will age well once the generation that they catered to is gone. And then there's the rare timeless work.
Leica gave her a camera. She is using it with an old lens she's had for years. From what I can see from several photos of her floating around holding the new Leica, it seems to be a Summitar.
collectors are starting to reject expensive inkjet prints in favor of analog prints (silver gelatin, Pt/Pd, etc.). I wonder if that might drive artists back into the darkroom.
I was speaking to a well-known gallerist/curator the other day and she told me she was recently speaking to an equally well-known photobook publisher and the both agreed that 'the days of the $2000 inkjet print are over'. Based on their opinions, at least, collectors are starting to reject expensive inkjet prints in favor of analog prints (silver gelatin, Pt/Pd, etc.). I wonder if that might drive artists back into the darkroom.
You haven't been to any galleries lately I'm guessing. I see prints (both darkroom and inkjet) that range from a few hundred dollars to 5 figures, depending on the photographer.
Based on the apparent age of Sally Mann in that shot, it may very well be that you would have to dig up and revive the photographer before the credit would be appreciated.
But yes, if the photographer's identity is known, please provide credit.
