One of the key tasks in any photography workflow should undoubtedly be “Editing”. Editing refers to the proper selection of the images that will compose a photographic body, which will respond to the specific purpose of the work's concept. Editing is often confused with everything done using computer software (to differentiate, this is “post-production”), which is also a key process. Contact Sheets gave a new meaning to my photography workflow. The technique is nothing new; however, they are an extremely intelligent way to start the editing process. A contact sheet is a simple page that contains a large number of thumbnails images in a grid. They were regularly used in the days of film, but their use started to fade away with digital photography. Contact sheets typically contained 35 images in 35mm format or 12 images in 120 medium format. Using these sheets, anyone could quickly see all the images from a roll of film. This practice made the act of image comparison a very simple task during the editing process.
