Wetpixel Live: How to Use Fisheye Lenses

@Alex_Mustard and @adamhanlon chat about one of the most crucial wide angle lenses in the underwater image-maker's lens bag: The fisheye. They discuss why this type of lens is so good for capturing underwater scenes, some tips on how best to use it, and why focal length is not all that it seems when talking about these types of lens.

Came here for the fisheye talk, came away with an order for the book. I've learnt a lot on this forum but the book isn't even expensive.

Makes  a change, right?!?
