|Glorious "Context" - Nubble Light at Dawn
I'm beginning to panic. This fall I'm scheduled to teach a class on digital photography for our local community education program and I have to get serious about putting together the materials. I have done plenty of talks for regional groups including camera clubs, Rotaries, Audubon Societies, and retired teacher groups, but I've never tried to assemble a reasonably coherent curriculum. Over the last year I have written several blogs about the basics of photography with the idea of covering topics that I could use in an introductory photography course, but now I have to get focused on putting it all together.My biggest worry is that I have no way of gauging the knowledge and experience of those who will sign up for the classes. I tried to aim my course description toward folks with an interest in learning about controlling exposure, focus and composition in landscape photography, but I could end up with some who are only interested in using their cell phones to take snapshots of their lunch. Its a crap-shoot, but I plan to combine classroom discussion with photo shoots and critique, it should be fun.
This week's blog is intended as another prep for the course. I plan to talk about how to approach a photographic situation and the first step is to recognize the quality of the light. Each type of light provides its own challenges and opportunities and working within those bounds can result in great images in any situation. So lets briefly consider a few kinds of light.

Golden Hour : Sunrise Sunset
|One Gull Short of Pretty, but BORING?
As is true in all landscape photography, the key is context and interest. When facing a spectacular morning or evening sky your first thoughts should be devoted to finding interesting stuff to put in front of all that color. Look for interesting foregrounds, reflections and framing to provide a sense of place and story. It is also helpful to show some detail in the silhouetted shadows. Expose to the right or consider a multiple image HDR rendering. Remember to keep the horizon line straight and away from the DEADLY, dead center of the image. It all comes down to the difference between a snapshot of some color and an image that allows the viewer to lean against that tree and fully experience the glorious moment. But there is much more to the golden hour than a crimson sky.
Turn Your Back On the Sun
Even mundane subjects can come alive when illuminated by the warm light of the golden hours. Don't forget to turn your back on that brilliant disc and take advantage of the soft glow which often contrasts beautifully with the deepening blue of the evening sky.
The Blue Hour
Unfortunately, many photographers arrive just at sunrise or retreat right after the sun dips below the horizon. The golden hour is lovely, but often the best light comes in the few minutes just before sunrise and after sunset. The "blue hour" is a great time to capture soft images without the harsh contrasts created by the unfiltered sun.

It is also one of the best times for night photography. A little light in the sky allows foreground detail to shine through and the blue sky is the best background for evening lights and the rising moon. The difference in feel between blue and golden hours could not to more striking and it is what makes sunrise and sunset such a rich time for a broad range of images.
Bright Sunlight - The Lead Hours
Stop Whining and Start Shooting!
After reveling in the glorious Golden Hours it is time to go from best to worst. Bright midday sun is universally considered the worst condition for landscape photography. Unfiltered overhead light creates harsh shadows, with impossibly stark contrasts and the rich colors of flowers and foliage are obscured by brilliant reflections. Perhaps the best approach is to take a nap until the sun begins to set. After all you did get up at 3AM to catch that heroic sunrise, but if you can stay awake, all is not lost.
A Beautiful Sunny Day
Midday sun is unquestionably the most challenging light, but non-photographers are always saying, "What a beautiful sunny day. You must have gotten some great pictures." We want to laugh, but there must be something these unschooled rubes are seeing that we smug photographers are missing. The truth is that the beauty is there, but the problem is in the limitations of our photographic tools to capture it.
Taming the Contrast
Bright sunlight produces harsh contrasts that were impossible to capture with the narrow dynamic range of convention film photography. Without the use of supplemental illumination such as reflectors or fill flash, the decision always had to be made between recording the highlights or the shadows, but things have changed with digital photography. The dynamic range of digital sensors is improving, but they still struggle with high contrast. The difference is in the ability to bring a precisely exposed images into powerful software which, almost miraculously, can protect highlights while salvaging detail in the shadows, and the blending of variably exposed images and the use of sophisticated HDR software has further expanded our ability to record the midday light. To me the greatest attraction of bright sunny illumination is the cool shade that it inescapably creates and now our images can languish under the tress without being oppressed by a surrounding curtain of blown out highlights.
|There Must Be Sun for Shade
It is the contrasts between light and dark that give "bright sunny days" their special attraction. Our job as photographers is to stop whining about the "terrible light" and start finding ways to push beyond the limitations of our medium, and capture the midday glory thiat is so apparent to everyone else.

Taming the Reflections
The rich colors of flowers and foliage are blunted or obscured by the reflection created by unfiltered sunshine, and sadly there is no perfect solution within current editing software. Midday is not the best time to capture macro images of flowers or the full glory of an autumn hillside, but, if you must, there are a couple of techniques that can help.
Given the right angle of the sun a polarizing filter can cut deeply into reflections and unveil the underlying color. Direct sunlight reflecting off most surfaces becomes polarized to a specific angle which can be filtered by rotating the polarizing filter to block that angle.
The degree to which a polarizer can filter out the glare is related to the direction of the light, being most effective when it is at 90 degrees to the subject. On the other hand, when the light comes directly from in front of the subject the effect is essentially nonexistent. Polarizers are often used on sunny days to darken the blue sky and highlight the clouds, but its real magic comes from its ability to penetrate the glare and when the light is right colors can explode in your images.

With the mix of light from the blue sky and the green of trans-illuminated foliage, color balance can be a challenge, but when shooting in RAW the color balance can be finely tuned. The sun can also be filtered or blocked with the use of a diffuser or your own shadow. Once again, the key is to get the diffuser as close as possible to the subject and to watch for distracting hot spots of bright light around the edges.
Trans-Illumination - Glory in the Brilliance
When all else fails, the bright sunlight can be used as a source of trans-illumination. Even the dullest foliage flowers come alive when strongly lite from behind and the back-light can create a shimmering rim light around the edges.

So the next time we are plagued with bright midday sun, avoid the nap, accept the challenge and find out why everyone else thinks clear skies and bright sun is so inexplicable beautiful
I've tried to suggest how our photography can accommodate what may be seen as the extremes of light, the glorious golden hour and the harsh midday sun, but the key to shooting in any light is to recognize what nature is providing and to modify our subjects and approach to get the most from the conditions.

Next week I will discuss a few more of my favorite "lights', including, overcast, fog, and extremes of weather. Hopefully this exercise will make it easier to face that room of students this fall and allow them to capture better iPhone images of their ham sandwiches.
