Good point but that's 90 degrees to the rollers, however I was out shooting 2 days ago and came across a similar lighting condition for a short spell, and shooting into the light was impossible.
In the shot in question the shadows are soft yet the top centre of the image is heavily burnt out, but it's not like bright sunlight it's more a wall of light.
What I found while shooting on Thursday, a bright mostly sunny day was some slight cloud suddenly took the blue sky reading from from Zone VI to about zone XI/XII, that's before taking into account the actual lighting on the subject had dropped. I suddenly had that wall of light behind what I was photographing. When the cloud passed I could shoot again despite the bright direct sunlight only just being out of the frame.
It's harder to describe than the reality.
