Preserving the view on a bright day
Often times the view is one of the most important feature of a home. I had the opportunity to photograph a house on the lake in Allyn, WA. Sunshine blasted through the windows, making it difficult to capture the view and the interior of the house at the same time.
You could use a flash and fire directly at the scene to brighten up the interior and set your camera to properly photograph the view, but it tends not to look good.
However, if you combine both images in photoshop and brush in the flashed image (and take another one with the flash at a different angle to get rid of the shadows and flash reflection), the final photograph looks realistic, preserves the view and interior.
