I photograph the same way I like to set up casting angles. Most photos of this bridge, any bridge will come from away down the middle perpendicular looking straight at the subject like a photo of a graduating class. That is generally not where I want to be for the cast or a snapshot. Casting angles start with boat position and the two combined are two of the most important considerations when you decide how to fish a location.
Excellent casts and interesting photographs, for me they work the same way, it's all about position.
