Abstract: A system for photography easily distributes slides onto a light transparent screen and subsequently regroups the slides into a stack with the same sequence, without need to individually manipulate the slides. The system enables a user to view many slides at the same time minimizing the area needed. The system comprises a transparent screen with a plurality of longitudinally extending rails which define columns for the slides and a slide dispenser box, for use in conjunction with the screen, which dispenses and collects the slides on the screen. The rails have an interior saw-tooth profile and the dispenser has a flexible barrier disposed over the dispensing opening which together allow for one slide at a time to be distributed and collected.
