Use colourful plants surrounding the exterior. Stand back and evaluate your home. Does it need colour or landscaping fill-in? Are there any eyesores that distract from the home?
Remember that when a home is photographed, lighting is very critical. Make sure you have light coming in from the outside so that the home appears cheerful and bright. Shooting with natural light rather than flash often gives a more desirable look.
Make sure photos are taken of those extra-special areas that make your home stand out, such as a sitting area in a master bedroom, the beautiful garden view from a window or a yoga/meditation room. Even if they're described in a written summary, capturing them with a photo speaks to people's senses.
Picture your home through the lens of a camera. Actually take a few photos with a digital camera. It's amazing what a camera can capture that the eye doesn't always see when the photo is being taken. You'll often find that a home is too cluttered; some furniture may need to be stored or moved to another room.
If you live in a Condominume/townhouse, virtual tours can be even more beneficial. because they'll also show common areas.
