I've provided training for corporate clients for some time (such as colour management and basic product photography), but after being asked several times I've decided to expand it to cover private individuals with specific topics like architecture, landscape and using tilt/shift lenses.
I'm only doing this relatively locally (Leicestershire, UK) but would be happy to include details of other working pro photographers who offer specialist personal photography training in other geographic areas.
With markets changing, I've long thought it wise not to put all my business eggs in one basket. Also, I've always found I learn something new myself when thinking about explaining technical or creative aspects of my work to others (it's one reason I started writing my articles/reviews)
Anyway, if anyone wants to swap some links - the directory page is at:
Photography training by professional photographers
Mail me via the site and I'll happily add other working pro photographers.
