30 Seconds at F22, ISO 100 (50mm).
I love it when I see photographs that look like they were painted on a canvas. Usually, the way to achieve this effect is with movement. Adding movement to a photograph can create the feeling of brushstrokes on canvas.
You might be surprised, but this was taken on a tripod. I stopped the aperture down to F22 to allow for a 30 second exposure to capture the force and movement of the waves and ocean. Although looking at it again, this print might need a little more film grain.
I've yet to print this, but I think it would look good on canvas.
