Team Induro member and renowned educator Jay Patel shares some insights on how to maximize the tonal range in your images:
When you see a stunning photo like the one below from California’s Redwood National Forest, you may wonder just how one captures images with such a wide tonal range?
Capturing an extreme tonal range in landscape photography often poses a challenge, even for the most experienced photographers.
The following are some of the techniques that we use to handle such a challenge.

Bracketing and Blending
Experienced landscape photographers likely solve this problem by bracketing and using HDR software or manual blending techniques to blend images in post-processing. Because this technique requires the camera to remain perfectly steady between the shots, we use a 2-second time delay and our rock-solid Induro tripod while bracketing out the shots. The downside of this technique is that it requires advanced post-processing knowledge to ensure that your photos have a natural look.
Using Muted Light
An easier way to eliminate the problem of wide tonal range is to simply wait for the right lighting conditions. Midday light tends to be harsh, forcing you to deal with deep shadows and blown highlights. Early morning or late evening light produces a narrower tonal range; overcast skies soften light even further. In many cases, your camera can easily handle that compressed tonal range. If you want to capture an image in-camera and avoid using software to blend images, take the photograph when the light is soft and even.
I took the two photos below in Washington’s beautiful Olympic National Park. The first photo of Sol Duc Falls was shot early in the morning, well before the sun was high in the sky. The soft light allowed me to properly expose every part of the image without bracketing or targeted blending to bring out the details in the water. I could have created an equally-effective image under overcast skies.
Soft, even light often requires a long exposure so we rely again on our Induro tripod and 2-second timer delay to capture photos like these.
Choice of Composition
Notice that the direct sunlight in the second image of the falls (above) creates harsh highlights in the bright areas and a lack of detail in the shadows. Although the rainbow is pretty, the extreme tonal range is more than the camera could handle, so the image doesn’t work.
One simple trick to deal with extreme tonal range is to pick the right composition.
I’m the first one to admit that this may not always be possible but, when it is, the results can be spectacular.
The following are two shots that were taken during filming our Behind the Lens course in New Zealand. The first photo with brilliant colors was captured by standing outside of and looking into the Cathedral Cave. The even light during that time of the day made the tonal range narrow enough to be captured by the camera in a single shot. The extreme tonal range in the second photo, shot by looking out of the Cathedral Cave, required bracketing and blending.
Using a GND Filter
If your horizon is level, you can use GND filters to tame the extreme tonal range. We carry a set of 2- and 3-stop GND filters to capture images like the following one.
This image in Death Valley’s Mesquite Dunes was captured using a 3-stop hard GND filter. Notice that the filter darkened the top of the mountains on the left but managed to reduce the dynamic range of the scene so that it could be captured in-camera using minimal post-processing.
