I found an old box of 4X5 Polaroid but once I exposed and processed it the prints didn’t look so good. About the time I was ready to throw out the box I noticed that there was an image on the negative.
Scanned it! Reversed in it Photoshop!
I feel by keeping the backing and mask around the image helps to renders the Polaroid as an object. The Polaroid images were made with a pinhole camera.
