Twilight Photography With Mixed Light Sources

Thursday, September 17th, 2009

The most recent class assignment for my students was an introduction to my favorite photographic time of day – twilight shooting!

You can certainly create interesting images composing solely with the natural light after the sun goes down. The warmth of sunset cools to a deep blue as the light fades below the horizon, forming a stunning backdrop for silhouettes. The colors in the sky itself, especially dotted with glowing clouds reflecting the sun’s last rays, make amazing compositions. Adding water or any reflective surface to mirror the light show going on in the sky creates yet another level of intrigue.

Still, it’s the playground of mixing man-made lighting with the waning natural light that will keep me fascinated for – well, I’d say hours, but it only lasts for 20 or 30 minutes! Unless you’re in the far north (or south, though I’ve not had an opportunity to shoot at twilight in Terra del Fuego – yet!) where the summer twilight seemingly does last for hours.

Exciting things happen when you mix the warm wash of tungsten light, the multi-colored palette of neon, and even the green glow of fluorescents and mercury vapor lights, against a backdrop of blue twilight.

While there have always been combinations of filters to adjust the tone and color balance to favor one source or the other, the advent of digital photography and instantly-adjustable white balance has made picking the right color balance incredibly easy. The classic FLB fluorescent filter, used to add that magenta glow that is never quite there in reality, can be mimicked by selecting the fluorescent white balance.

You can try every combination of white balance settings right there one after the other, and pick the one you like. Not to mention shooting in RAW and making minute adjustments in post processing.

Did I say digital photography makes it easier? Now the challenge is deciding which look is the “right” one for your eye. At this time of day there really are no rules. It’s “photographer’s choice”.

So grab your tripod, go out this evening and play!

Everyone Has Their Own Unique Creative Vision

Monday, September 7th, 2009

The students in my class have given me permission to share their photos here, so I thought I’d show a great example of a concept I always emphasize about personal vision and creativity – that two people can stand in the same place and each make a very different photo of the same subject. Here are the photos along with my comments.

Two images of the same subject, different interpretations!

Both of you used selective depth-of-field effectively. (That is, they used a large aperture to isolate and emphasize a subject. I’ll be talking about this and other terms in the next few lessons, so if you don’t understand them right now, hold on).

Courtney is focusing on the text and design on the bench. The out-of-focus arm in the foreground causes the eye to seek something in-focus, leading us to the designs. (This is a phenomenon called “Visual Weight”, where your brain expects that something in-focus has more importance than an out-of focus area, and your eye is drawn there.)

Our eye continues to move up and back, drawn by the shape and color contrast of the violet wall against the cyan bench. The shape of the wall section leads our eyes down to the far arm of the bench, where the lines of the boards in the bench and the contrasting dark spaces in between them lead us back to the out-of-focus foreground, where the process repeats.

The color contrast and shape of the single vine on the wall reinforces the movement. This is of course a found element (I assume you didn’t rearrange their landscaping for the shot!) but that’s what looking and learning to see is all about.

The strong color and tonal contrast of he far bench arm and background could lead the eye out of the frame, but the strength of the other elements has more influence and actually causes the arm to lead our view back in from that side of the frame.

Ruby chose to emphasize the color contrast of the worn paint on the arm in the foreground by placing her focus there. The soft but still-understandable text and design on the bench, plus the lines of the boards and spaces, lead the eye up and back. As the focus continues to soften visual weight pulls our eye down and back to the front of the bench where the paint contrast is repeated and the increasing focus and the line of the front edge of the bench leads us back to the foreground arm.

By cropping in closer on the bench and eliminating the wall, she avoids the color contrast that would want to hold our eye in the background.

Two different interpretations of the same subject. Both work. Neither is right or wrong.

Both of you use the Rule of Thirds effectively in your composition (both here and in your other photos).

One of the most fundamental concepts of composition in art, going back at least to Greek writings on art and most likely understood instinctively even before that, Is the Rule Of Thirds. Here’s how it works:

If you draw lines dividing the image into thirds both horizontally and vertically, he important elements of the composition should lie on those lines, and the points of greatest interest should be placed where the lines intersect. This creates a dynamic balance that has more energy and movement than a completely centered composition, which tends to be more static, more restful and peaceful.

 Here’s what it would look like:

As I mentioned in class last week about “rules”, this doesn’t need to be followed with absolute precision, and there are times when you may want to ignore it completely. Think of it as the “Suggested Guideline” of Thirds.  It works as a good general guideline, much of the time. But don’t get locked into it and be afraid to experiment with other compositions. Remember, it’s all about what you are trying to communicate with your image.

 Some cameras now actually have a display setting that will project this grid onto your LCD and/or viewfinder to help you see it. Even without this, seeing it becomes easy and intuitive with practice.

 One reason this placement of points of interest works is that it creates a diagonal within the frame for the eye. Lines are an important and probably the most common element in design, and diagonal lines are very powerful, creating movement to draw and guide our eyes.

Everyone found these insights extremely helpful as you learn to see your world in a much more creative way. We’ll be taking a look at more examples of the students’ work and what we’re talking about in class in coming posts.
