Viewfinder is an invaluable resource for almost anyone who uses a camera. Whether you’re a cinematographer, photographer, or even a painter, chances are good that you use some type of viewfinder to help visualize your subject. Maybe you like a professional grade director’s viewfinder, or perhaps you’re a little more old school and prefer an old fashioned cardboard cutout. With Viewfinder, you can have the best of both worlds in a single powerful, highly customizable, easy to use iPhone app.
