The sun was a fiery orange ball setting in a North California sky hazy from forest fires. I ran out with 400mm of telephoto (600mm in 35mm terms) and focused on plants in the foreground to take advantage of the dramatic solar appearance.

Surf and Stars

Wednesday, June 25th, 2008

We’ve had a couple of spells of really warm weather lately. This is an unusual pattern for the San Francisco Bay area in summer. It is well known that summer weather in San Francisco is often cold and foggy.

On one of these hot and sultry summer days Mark and I started down the trail for Tennessee Beach well after sunset. It was night by the time we reached the ocean. The stars were out and the moon hadn’t risen yet. It was cool and relaxing after the hot day sitting on a ledge above the beach in the darkness.

I made four exposures while we sat and chatted. Everything looked dark, so I was surprised to see oodles of color in the LCD screen after each exposure. No matter how many times this happens, it always surprises me. In an apparently dark and monochrome world, there are transcendentally beautiful colors.

Vincent van Gogh put it this way: “It often seems to me that the night is much more alive and richly colored than the day.”

Where do the colors in these images come from? I’ve two theories: possibly the colors in the clouds are ambient light from the city of San Francisco, reflected off clouds and around the bend. Also, some of the colors may be left over from the sunset. I’ve noticed that these colors do grow less vivid as the night progresses.

Our human eyes simply don’t have great sensitivity to the light waves that are present after sunset. (Vincent van Gogh may have been an exception.) Digital sensors do, and maybe animals of the night see these colors as well.

At a recent workshop I gave, I was asked whether I worked to recreate a scene the way I saw it when I was there. I answered, to a certain amount of gasping, that actually I didn’t care what a scene I photographed “really” looked like; my concern was for the way my imagery came out.

Of course, the merits of photographic fidelity to a subject depend on the goal of an image. Journalistic photographers and documentary photographers are correctly held to a standard of recreating the actual look of their subjects. On the other hand, advertising photographers have the intentional goal of misleading by exaggerating the visual benefits of the products they shoot. I believe, as a photographer with the stated goal of creating art, that what “was there” when I took the original photo is essentially irrelevant.

One reason I use the term “image” to describe the pictures I make, rather than “photo” or “photograph”, is to say that my work cannot necessarily be regarded as a literal depiction.

It takes work to tease these colors out of my RAW files. True, I couldn’t tease them at all if something wasn’t there in the first place. But still, in someone else’s hands these images would be processed very differently.

For me, I care far more about the final visual result than the classification of the technology used to create the image. I’d be happy to use digital photography and post-processing to make night landscapes in the tradition of van Gogh’s magnificent Starry Night. What you see is not always what you get.

At one time one of the longest bridges in the world, the John F McCarthy Memorial Bridge is a double cantilever structure stretching across the San Francisco Bay from Richmond to San Rafael. Certainly not the most glamorous bridge across the Bay, the snake-like twist in the structure adds visual interest, particularly under cloudy night skies.

Mount Tamalpais from Corte Madera Creek

A long, happy, tiring, and exciting day began for me with a visit with my three boys to Katie in the NICU. I then spent the afternoon giving a digital landscape photography workshop to full house of enthusiastic photographers under the auspices of the Point Reyes National Seashore Association.

If you are interested, I’ll be giving this one-day digital landscape photography seminar again on October 26 in the Red Barn at the Point Reyes visitor center. I’ll post more information once a registration link is available.

Afterwards, as darkness covered the landscape, Mark and I wandered around taking pictures.

This image is from the tidal flats near Larkspur, by the banks of the Corte Madera Creek, looking back towards Mount Tamalpais. I was trying for a frontal view of San Quentin prison at night from the mud flats, but saw this neat night vista behind me.

While it was pretty much night, there was plenty of ambient light from the Marin cities, as well as a half moon. The interest for me in this photo was the way the various kinds of light mix to make an interesting melange of colorful night.

In 1995 the Vision Fire burned more than 12,000 acres of Point Reyes National Seashore. Fierce Santa Ana winds blew the resulting smoke plume a thousand miles out sea (here’s a satellte photo of the plume).

Today, thirteen years later, the burnt trees stand like sentinels against the sky while new growth has sprung up all around. This year, alas, the poison oak is particularly thick in the clearings.

Wildcat Peak Sunset

Wildcat Peak Sunset

I went for a walk at twilight, hoping to clear my head after the excitement of the last few weeks. Sea-born clouds and fog were ramping quickly into the coastal range, so I didn’t have too much hopes for photography. Still, I brought my photo gear, because you never know.

Turning the corner on the trail, I got a view of Wildcat Peak with the disk of the setting sun visible above it. By the time I got my camera out and was in position, the sun had vanished in the fog. I held on to the bitter end. The sun appeared, setting behind the peak, at the last.

I took care to expose for the sun itself, letting the foreground go dark (because I know I could fix this in the digital darkroom, and I didn’t want the sun to blow out). Fix or no fix, much of the drama of this photo is in the contrast between the setting sun and the dark hillside.

Star Circles 2

Star Circles 2, photo by Harold Davis. View this image larger.

This is my second forty minute exposure of stars circling over the Point Reyes the other night. The original version was horizontal. As this exposure progressed, low-flying clouds were sweeping across the sky, softening and darkening the scene. At the extreme left of the photo, a working boat on Tomales Bay flooded the scene with light. Time passed.

On a technical note, it’s pretty tough to accurately gauge exposures from the LCD at night because the display compensates. It might look decent on the screen, and still be four stops underexposed. So the exposure histogram is a better way to tell if your exposure is in the ball park. It’s unrealistic at night to expect nice, bell-shaped histograms in the middle of the range. But if your histogram is totally clumped on the left, you have a problem.

I glanced at the histogram for the previous exposure, and lightened things up a bit, moving from f/13 to f/10. Had I known the scene would darken as much as it did (because of the clouds), I would have opened it up at least another full f-stop.

Angel Island Views

Golden Gate Reflections

There was a strong wind blowing at my Angel Island campsite, and my tent puffed in and out like a bellows. But a little after midnight, the wind totally cut out and the surface of San Francisco Bay turned as flat and reflective as a sheet of glass. I grabbed my camera and tripod, put on a polarizer, and got a bunch of exposures before the wind picked up again and the glorious reflections vanished.

Some hours later, emerging from my sleeping bag, I saw the rising sun kissing the top of San Francisco’s towers.

Camping on Angel Island

Campsite #4

I spent a night last week camping on Angel Island. Smack dab in the middle of San Francisco Bay, wild in the midst of civilization, I had a great time. You can only reach Angel Island by ferry, and after the last ferry left I had the place pretty much to myself. I climbed Mount Livermore, and then settled down at my camp.

Perched on the southwest corner of the island, I had drop-dead views of Alcatraz, downtown San Francisco, and the Golden Gate. The show started at sunset, and did not stop. More photos will follow.

I took this one a little after midnight. There was a huge old Eucalytus tree stump at my campsite. I exposed for the Golden Gate Bridge, and lit the stump (which was in deep shadows) during the exposure by “painting” with light, using my headlamp.

Monochrome Shore

Monochrome Shore

Monochrome Shore, photo by Harold Davis. View this image larger.

I’ve been thinking a good bit lately about making black and white prints from certain of my digital images. Actually, since the final output would be using my digital printer, printing via offset, or display on a color monitor, what I’m really doing is to use the RGB (or CMYK) color notation to create a simulation of a black and white image. So this is an intentionally retro endeavor. Worth noting: quality vintage black and white prints were not actually “black” and white, but toned to create a rich (but monochromatic) look.

I took this photo from a position some way off the Chimney Rock Trail in Point Reyes, look west at the setting sun and the rugged shore of the end of the Point Reyes peninsula. My intention when I took the photo was to convert it to monochrome, because there were hardly any colors anyhow. The shoreline seemed backlit to me, and I figured, well you can get a glamour backlit black and white of a model, why not a landscape?

Taking the photo took a fraction of a second, but converting this image took much longer.

First I processed it from the RAW as I would a normal color image, using several different RAW “exposures” in combination. Next, I tweaked each color channel used Color Channel adjustment layers with monochromatic check. I weaked the whole confection a bit, then added a few adjustments in LAB color and a tritone version of the original on top of my (by now massive) layer stack. Not to oversimplify, I used a variety of blending modes, masks, and adjustment layers.

If there is a moral to this, it’s that the key word is “simulate.” To get the “black & white” results I wanted, I needed to alter the color structure of the image, creating an entirely new look in the process. Well, honestly, that’s what I normally do with my photos much of the time.

Scalloped

I stood on the bluffs high above Drakes Beach just after the sun had dipped below the horizon. The high bluffs shadowed the beach below, while the light of sunset still reflected from the incoming surf. I shot a sequence of images at various shutter speeds.

If you are curious, the faster shutter speeds came out better than the slower ones at the same EV value. Across the board, I intentionally underexposed by about two f-stops (or by a factor of four) to make the beach go even darker while still picking up the colors in the water.

Back at home, when Phyllis and I looked at the sequence in Adobe Bridge, the thumbnail looked to us like a scalloped sea shell on a black background. I processed the photo in Photoshop to emphasize this effect.

Country Road

Country Road

Country Road, photo by Harold Davis. View this image larger.

The verdant emptiness of the Point Reyes peninsula is achingly beautiful just after sunset.

On a recent weekday, there was no one around. On my way back from the Point Reyes lighthouse and Chimney Rock, I paused on a rise beside the road. The fresh air was redolent of the ocean, with a tang of dairy farm and fresh grass.

I set up my tripod near the road, with the assumption that no car was going to careen over the rise into me. Then a lone car came over the hill, went wide around me, and I pressed the shutter for this fifteen second exposure.

Next, it was on to Inverness to photograph the star trawler.

Pole Star

Pole Star

Pole Star, photo by Harold Davis. View this image larger.

This is the last of a sequence of twelve photos of the wrecked Point Reyes trawler near Inverness. I took these photos the other night over the course of a couple of hours. The sequence started with The Long and the Short, and included Star Trawler. Like Star Trawler, this last capture in the series is a 1,204 second (20 minute) exposure.

As I was taking this photo, I was interested in the reflection of the boat in the water. I’ll admit I was pretty bored with all the waiting around during the long exposures and the in-camera noise processing, so I augmented the reflection with a little discreet light painting on the hull with my headlamp.

I also angled my camera so that it was facing due north and the Pole Star. The Pole Star, also called Polaris or the North Star, is almost stationary in this photo while all the other stars trail around it. This is because the Pole Star lies nearly in a direct line with the axis of the Earth’s rotation “above” the North Pole.

It has been rudimentary night-time navigation for thousands of years in the nothern hemisphere to determine north using the Pole Star (and is still useful if you are lost in the wilderness at night without a GPS or compass).

To determine north, first find the Big Dipper. Next, locate the “cup” part of the dipper so you can draw a mental line extending from the star Merak and extending beyond the star Dubhe (you’ll find a diagram in the Wikipedia article). The extended line will point at the bright Pole Star (it’s about five times as far from Dubhe as Merak and Dubhe are apart). Draw a line from the Pole Star to the earth, and you’ve fairly accurately found north.

This explains why I was excited when I spotted the Big Dipper pointing to the Pole Star directly above the wreck of the Point Reyes. I was hoping to capture the stars whirling around the single still point of Polaris above the boat.

The Long and Short

Star Trawler 2

This is my first, and shortest, exposure of the Point Reyes boat the other night. As I explained in my original story about the star trawler, I was surprised to find the apparently monchromatic moonlight producing such vibrant colors.

The longer exposure was intended to produce star trails, but I like the effect here too: of stars more the way we see them.

The pair of photos illustrates a spread of aperture-shutter speed combinations, both at essentially the same exposure value: from 1,204 seconds at f/22 at the long end to 30 seconds at f/3.5 at the short end. (”Long” and “short” refer to time.) Since depth of field is not an issue in these photos, the contrast is a good illustration of the differing way exposure time treats objects in motion (the stars).
