I do occasional real estate work. I take great care to ensure properties are properly photographed - well lit, no extraneous items in the photos (e.g. rubbish bins and miscellaneous clutter) and that vertical lines are vertical. I use a combination of natural light and flash and blend the exposures in Photoshop. All this is done with one aim in mind - to show off the properties to best advantage. This is a random sample of images from several different houses.
