If you ever wanted an easy way to merge three photos with different exposure settings taken from the same scene together to one image with a well balanced dynamic range - well here is the solution.
Shoot three images of one scene (with a tripod) with an exposure difference of 2-3 between two pictures. The middle one should be taken at the [P] (automatic) setting of your camera, then an over- and an underexposed one.
And be sure not to alter the aperture setting! Solely adjust the shutter speed because otherwise you would get different depth of field values.
