Peter White is blind.

His job as a broadcaster has taken him all over the world.

At first he thought that he was missing out on not being able to see the standard tourist monuments, but when he travels now he has an arsenal of strategies to get to know a place.

He listens to local radio, he takes in the sounds of restaurants, travel systems and the voices of the locals.

In this two-part series he travels to San Francisco and Istanbul - what does he discover about these cities?
