Before Polaroid went bankrupt, and Kodak still produced slide projectors, popular photography generally involved shooting 35mm film, and letting it be developed like magic on 4 by 6 inch high-gloss paper. Many processing providers took the liberty of editing the photographs for the client — film that was ill-lit or blurry were tagged with a wax marker across the center, resembling a skid mark of black soles on a white floor. By burning ones index finger with friction, this mark could be removed…I however, now say thank you to those now-unemployed photograph clerks for making my art for me.
