Lighthouse Beams Across Stormy Sea - My Vision

(Click on image for a larger view.)

The Oregon coast is one of my favorite vacation spots, and Heceta Head is probably the most photographed lighthouse in Oregon. Some of the most beautiful photos are taken at or near sunset. However, in this image I wanted to show the real purpose of a lighthouse: to guide seafarers at night. (I'm a stock photographer, and conceptual images SELL better than "pretty" pictures. I've also learned to leave room for type.)

To make this iconic image, I started with Kodak Ektachrome film, using a Nikon FM2, with a 200mm lens. I used a Kodak #47 (dark blue) Wratten Gel filter in front of the lens to enhance the feeling of a night time scene. The base exposure was 1/2 second @ f4 - followed by 16 separate exposures of the rotating lighthouse beam: I held a black card in front of the lens, and every time the beam rotated to the left position and flashed across the ocean, I pulled the card away from the lens (which was now stopped down to f11). The 35mm vertical image was then scanned and cropped to this square format.

One might think that this image could have been taken much easier if I had done it digitally (the way all my photos are taken now), but that's not true. The multiple exposure steps would be the same. The only change would have been the blue filter -- which is a simple step in Photoshop!

Moonlight Reflecting Across the Ocean - My Vision

"Moonlight" across the ocean ~ © Royce Bair (Click image for a larger view)
This photograph was from the deck of a cruise ship, while cruising the Mexican Riviera in early December. I was teaching a photography workshop on this trip, and I took this shot in between classes. The idea in my mind was to create a romantic, moonlight evening view of the ocean, as one would see from the elevated deck of a cruise ship.

This shot is only an illusion to the nighttime. The image was taken in the daytime, with the sun just outside the camera view, so I had to shade the lens with my other hand. Photographing the reflection of real moonlight across the ocean would have required a time exposure that would have blurred the ocean waves to almost complete smoothness -- not to mention the fuzzy horizon line due to the ship's motion. This illusion is similar to how movie makers do "night" scenes -- underexposing the scene and using a blue filter, or changing the color balance in post-production. Note: in the early B/W days, a red filter was used, not to change color, but to increase contrast in the B/W image.

The original photograph was mainly shades of gray, with very little color. Post-production of the raw image in Photoshop changed the scene into millions of shades of blue. The sky also had to be darkened considerably. The final touch was to give the image a slight pinch-cushion distortion to increase the curvature of the ocean horizon. This less than 3% curvature has an amazing effect on the mind. The image becomes less static, more recognizable, more memorable, and more exciting.

I photographed some stunning locations on this trip, but this simple, conceptional icon has made more stock photo sales that any of the other images I took.

September 2012 update: A real moonlight shot is now possible with some of today's new high sensitivity DSLR cameras (full-frame sensors, capable of high ISO's and low noise), such as the Nikon D4s and the Canon EOS 5D Mark III. However, the results would still be very noisy. Let me explain: Daylight is about 300,000 times brighter than moonlight. The above daylight photo was taken at an exposure of f/18 @ 1/500 second, ISO 100. A similar moonlight shot would have had to have been taken at ISO 30,000,000! Since both of the cameras mentioned only go up to ISO 102400, I'd suggest a more reasonable exposure of f/1.8 @ 1/60 second at ISO 29,297 (or the camera's closest equivalent of 25,600) -- which would still be very noisy.
