Backdrop Designer is a new Photoshop plugin that allows you to create resolution independent backgrounds, similar to what you find in expensive muslin canvases used in photography studios.
Use Backdrop Designer to insert 100's of different pre-made backdrops with one click. Modify them with lighting effects, 3D distortions, shadows, and color choices. Or, combine the presets to create your own unique backdrop.
Digital backgrounds can make commercial photography more flexible, because your clients are not limited to an image decided upon before their photoshoot.
