Here’s a lighting challenge: A freight train crossing a big bridge against an overcast sky.
Expose for the train and the sky gets washed out (loss of detail). Expose for the sky and the train is too dark.
So what do you do?
I expose for the sky and then adjust the file in post processing.
Why? Because it is easy enough to lighten slightly underexposed areas, but once highlight detail is lost through over exposure it cannot be recovered.
To balance the exposure in post processing, I lightened the shadow areas globally. This took all of about 30 seconds to accomplish in Lightroom. I also made minor adjustments to overall color balance and saturation. Afterwards, I played with the file to make some outlandish versions for point of comparison.
Of the four, the second from the top is the only image I’d normally present. The bottom of the four is intended to be a little absurd.
