They're professional photographers, usually well known and published, all with outstanding travel photography experience and a portfolio to die for. We insist on local experts: we don't ask or allow photographers to lead tours in territories in which they do not have a considerable amount of shooting experience.
Usually, that means they're locals — Indians in India, Turks in Turkey. Where that's not possible, we still insist on pro shooters who are or have been residents, who speak local languages and are embedded in the local culture — or, at the very least, have been shooting there for years.
The big reason for this is, frankly, that local experts have the ability to deliver those privileged encounters and special shoot opportunities. They usually speak the local language, and that breaks the ice and gets us into the shots. And they know precisely how to connect you with the local people, customs and stories — and to do it in a respectful, responsible way. More here.
