Adding Drop Shadows to Your Real Estate Photography in Photoshop

Realism, depth, and perspective are just some of the words that will probably describe how an image in real estate photography can exude more impact. A photo that presents itself as a 3-dimensional image compared to a flat 2D render would more likely gain a better following as a result of appealing to aesthetic perceptions. Drop shadows is a perfect way to put that perspective in place. This technique that is available in most real estate photo editing software enables objects and elements to pop out, creating a distinction between two different planes of sight.
