One of the interesting things about the low level shots is the way that the low angle changes the Depth of Field. The marker buoy you see in the two low angle pictures looks so much bigger than it really is. It also looks closer. An optical illusion caused by the buoy blending into the distant horizon...( I think
) If you look at the second picture of the boys fishing .. you see the same buoy and it looks "normal" size, because it doesn't blend into the shoreline.. ( I think
)
