This image, unique from the others in this series, comes from a 35mm Black & White infrared film negative re-photographed onto a Type-55 Polaroid neg. Remember a negative of a negative creates a positive image. In order to create a 4x5 Polaroid image from a 35mm original, you need a special piece of gear (or alternatively you could achieve similar results in a B&W darkroom with an enlarger).Years ago I was asked to teach a six-week course of adult education on all things Polaroid. So I created a course that took the students through the various ways of creating artistic images with Polaroid films. 
One of the key tools for re-photographing 35mm images (slides, color negs, Black & White negs) is a portable enlarging device called a Daylab. So, while prepping for this course I created a variety of sample images to show the possibilities of Polaroid images. This image was one, and as much as I love infrared landscapes, I wish for larger format film, which doesn’t exist. So this is the way to enlarge an image to use various Polaroid films for the beautiful qualities only Polaroids have. I love the addition of Polaroid edging marks, and the unique quality inherent in Polaroid emulsions and adding those qualities to infrared film images. It’s a glorious combination.
