A few months back, I had a photo shoot in an empty house with wood floors. In post-processing, I noticed what a poor shot it was. Recently, this happened again. The dark/light extremes and exposure are really kicking me in the pants. In post, I can bring the exposure up but I really get unnatural results. Any suggestions on how to shoot a bright room with shiny wood floors in vacant houses that don't have any drapes or curtains?
The best way to handle shiny wood floors is to speed up your shutter speed to kill the ambient light (reflection) and then flash the room. If you are using HDR or straight ambient, you’re most likely going to be stuck with those reflections.
In this empty room shot above, I was using one flash, ISO 400, 1/60, at f/5.6. I could have gone much faster with the shutter speed to reduce the reflection but I wasn't concerned that much with the reflection. I did have some control of the window light.
