3 Core Elements of Controlling Tonal Value.

By Gavin Seim

I’m amazed how often the control of light and dark is ignored in today’s photography. Our tools are more powerful than ever, but most images lack the subtle tonal control that made photographers like Ansel so famous. Such control is essential to making an image look as good as it can.

“Tone” may be the least understood and least utilized factor in composing and finishing images.” That’s a quote from master photographer, Ken Whitmire. He’s eighty-two and one of the world’s most renowned pioneers of wall portraiture.

I wrote an article called 5 Essential Keys to Photographic Perfection on Pro Photo Show. One of these keys is arguably the most important, and that is tonal control. Lights and shadows and how they look in the final image are critical. To best achieve them, you should have a “visualization” for your final image and be a master of essential tone control elements.

Morgan's Song, 2011 - This is an environmental scene so we have a lot of "supporting cast" to deal with. By placing the subject at Zones 6-8 in the final process and the supporting cast mostly in Zones 2-4, I was able to keep the subject dominant and show the scene I had envisioned.

An image can look good with just a quick global correction process, but not nearly as good as it could be with proper tonal control. It starts in camera as you see the scene in your mind’s eye . The way you expose and set up your image can control those values. The best way I have found to see this in my mind is by using the Zone Scale (see Fig. 1).

For example, a perfect light is splitting through the clouds and shining on your subject. You expose for the subject’s skin, visualizing it for Zone 6. Perhaps that bumps the foliage and other elements (the supporting cast) of your scene down to Zone 4. That could be perfect because it makes your subject dominant. Perhaps the light is more even, however, and to achieve that visualization, you need to do tonal corrections later to bring that foliage down to Zone 4. It could be done in many other ways, but you get the initial idea. For an in depth look at Zones check out, Why You Need the Zone System for Digital.

Following are three things to watch for when visualizing and mastering an image to control tonal values. If you understand and apply these principles at every step, your images will improve by giant leaps. Follow through on tonal values and your images will sing.

5 Essential Keys of Amazing Photographs.

By Gavin Seim

Simplicity is key to a great photograph. It turns even complex scenes into stunning beauty by controlling elements, light, and tone.

It’s not about how much is in a photograph. It’s about how we showcase our subject in relation to that supporting cast of elements. Now I’m not suggesting the images I show are “perfect.” It’s rare that I get everything dead on, and I can always find something I should have done better. But truly understanding and mastering these elements WILL raise the bar on our images and allow us to see in a new way.

1. Visualize.
Everyone says they’re doing it, but few actually are. You should truly “see” the scene in your mind’s eye; not what’s in the viewfinder but the finished image after the exposure, even after editing. You should see the image you want after the process is finished. It’s fairly simple, but in the rush we often fail to slow down and think carefully about the lines, elements, and tones in our scene. That’s one reason why I love working with a tripod. It takes my focus away from holding a camera and puts it on the scene in front of me.

Ansel Adams said, “The whole key lies very specifically in seeing it in the mind’s eye which we call visualization.”

Sunsets Hidden Falls, Yosemite 2010, Gavin Seim - I used a layer based HDR process on this, processing my light and dark frames as silver and layer blending in Photoshop. I spent a good deal of time on the composition and tonal control to try and keep the scene simple while still showing all the elements. You can see the stone faces on Zones 6-7, with the foreground elements falling drastically all the way down to Zone 1, keeping them as supporting cast from becoming too distracting.

 

2. The Light & The Zones.

Expose for what you want in your image, not what the camera sees. This goes right along with visualization, and the Zone scale is the best way I know of, both to visualize and to control values. It allows us to see in our mind’s eye the Zones in a scene and place them where we want, using exposure, and finally tonal edits. For more on detailed tonal value control, see the counter article to this one, 3 Critical Elements of Controlling Tonal Values.
