A story behind: The whole last week the sun was shining furiously with no clouds in view. Finally last Thursday some small clouds appeared so I grab my gear and headed to the beach to test my new shiny camera and lenses.
Location: Foz do Douro, Portugal. Atlantic ocean sunset.
Gear: Nikon D700, Nikkor 16-35 mm AF-S ED, tripod. RAW to Tiff B&W conversion. Vignetting with a +21 midpoint added.
