Most of our interiors photos are actually multiple photos blended in Photoshop. The natural light and shadows of the room are combined with images taken with an off camera flash. We never have a flash attached to the top of the camera. Care is used to properly expose for the “out the window” view. Harsh shadows from the flash are minimized or completely eliminated. We straighten the things that need to be vertical like doors, windows and walls. We will replace gray skies with blue skies on the front shot when possible.
