SECRET SEEDS 1985 is a tryptich sketch photo collage created from photographs of a cover of a National Geographic from 1983. It is an image of a Wodaabe man of the south Sahara, photographed by Carol Beckwith in 1983. Each section is a separate exposure on color negative film, printed on color C type paper, and mounted onto black museum board. The motion is created with manual camera movements. Unpublished, I created it to work out some ideas and techniques for other projects.
MURGATROYD IN RETROGRADE 2017 is a work-in-progress, photographed at the Monterey Aquarium. I’m not sure if it is 90% or 10% there…. Here is a glimpse at process: 
BRYANT PARK SKETCH 1997 is an unrealized analog photo collage from the 90’s Collage era. Typically I am cutting off the sprocket hole edges and taping them to glass to make the final contact print. It is shot with Ilford XP-1 chromogenic B&W film and printed on color c-type paper.
SPRING BREAK SKETCH 1995 is a very preliminary sketch for one of the Kodak Funsaver ad campaign shoots entitled ‘Spring Break’. One of a series of ads created for Kodak thru J. Walter Thompson. They are analog photo collages, all shot with Kodak Funsaver disposable cameras and printed at local one-hour photo labs.
this is a preparatory sketch for CIRCLING THE DRAIN 2016. It is a digital photo collage made from imagery found on Google Earth. For more similar images, look at Google Hack on my website.
TULIP COLLAGE 2006 is a digital photo collage from images shot with a Canon G6. A ‘Quickie’, photographed at the New York Botanical Gardens. I used camera motion during long exposures to create painterly feel.
PANTHEON DUE is a digital photo collage made from imagery found on Google Earth of the Pantheon in Rome. Loose and sketchy, like this loose and sketchy film version I did in 1987. For more similar images, look at Google Hack on my website.
WINDSHIELD SKETCH 2007 is a digital photo collage from images shot with a Canon G-6. Photographed while driving up the West Side Highway, using long exposures. Please – photograph responsibly.
88-111 (The Man in the Boat) is a digital photo collage made with files shot with a Nikon D750. It is a revisit of earlier analog collages Boat, Cape Cod and Paula, Montauk.
The Guggenhein Sketch Strip here was created at the same time I shot Guggenheim. They are both large scale contact prints, shot on Ilford X-P1, a black and white chromogenic film, and printed on color paper. I had this in mind:
