Ever been forced by circumstances to shoot a real estate front shot with a vehicle sitting in the drive way? I have; I see cars in the driveway of real estate front shots all too much. They distract from the purpose of the photo. But I also understand that you can be forced to choose between another trip to the property and shooting with the car there because owner of the car is not available to move it.
If you are not up to removing cars with photoshop there is another alternative. You can have cars professionally removed from photos by wowapic.com. I would wager that, at todays gas prices, having wowapic.com remove the car is cheaper than a second trip.
Wowapic will also do other more involved image editing tasks that may be beyond the Photoshop skills of a busy Realtors or beginning real estate photographer. They will do the editing at your favorite photo sharing site. Wowapic.com is worth a look if you don't have the time or skills to do all your photo editing.
