dynamic range - How can I get the right exposure when parts of the scene are in the shade and others are in the sun?


Have a look at these snaps. On the first one the church has the right exposure but the tree is too dark. On the other hand in the second one the tree is perfect but the church is too bright.


Is there any technique/parameter setting i should use to capture both things with the right exposure?


Right Exposure for the church


Right Exposure for the tree


Thanks!

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.
