How do I expose a high-contrast scene with sunlit and shaded areas?

I photographed a scene where part of the subject was in direct sun and part was in deep shade. In one exposure, the sunlit church looks correct but the shaded tree is too dark. In another, the tree looks good but the church is too bright.

What’s the best way to handle this kind of high-contrast scene? Is there a camera setting or technique that will let me keep detail in both the highlights and shadows?

It looks like the first one has the right exposure. Not only is the church properly exposed but the tree has not lost details except in the darkest shadows.

If you wish for the tree to be brighter then you will be able to adjust things using a post-processing software (look for levels, curves or something similar). Since a camera sensor has a fixed dynamic-range there is nothing much you can do about controlling all the tones in a single shot.

For the times where the dynamic-range of the scene is too high, people use Exposure-Fusion or HDR which requires multiple shots taken and merged by software to capture details across all tonal ranges.

This is a dynamic-range problem: the scene has more contrast than the camera can capture cleanly in a single exposure.

The safest approach is to expose for the bright areas so you don’t blow the highlights. You can usually brighten shadow areas later, especially if you shoot RAW, but clipped whites usually can’t be recovered.

In your example, the exposure with the correctly exposed church is the better starting point, because the tree shadows still appear to hold detail.

Ways to improve it:

  • Shoot RAW and lift the shadows in post-processing.
  • Use shadow/highlight, curves, or levels adjustments in editing software.
  • If your camera has a feature like Highlight Tone Priority or Active D-Lighting, it may help protect highlights while opening shadows.
  • For scenes with extreme contrast, take multiple exposures and merge them with HDR/exposure blending.

So: protect highlights first, then recover shadows if needed. If one shot can’t hold both, bracket exposures and blend them.
