My apologies for spoiling your Sunday, but here's a sobering interview by Simon Norfolk on the World Press Photo website.
I would say that two of his predictions for the future are ones that forward-looking photographers have certainly realized for a while, and have acted upon already. There are quite a number of "masterclasses" that have sprung up recently, such as Gary Knight and Philip Blenkinsop Master Classes for instance. I have no idea if these are aimed at "wealthy orthodontists" or not, but that's the general idea.
"So my predictions for the future? More "name" photographers will be cashing in their reputations to teach "masterclasses" to wealthy orthodontists.
None of us will be saying "no" to wedding photography or lucrative teaching posts which sell to young students the rarely-realized dream that they’ll one day have jobs as photographers."
Some of us will perhaps deem Simon Norfolk's view as being too pessimistic or cynical. I, for one, see it as realistic.
However, let me also point out there are some of us who accept short-term teaching posts for no pay...such as those who have lined up to teach at the Foundry Photojournalism Workshop.
