A frame (20), for illuminating a depiction on a transparency (50) with full illumination or with highlighting, shadowing and dramatic illumination, includes a front panel (36), a back panel (38), a bottom lens panel (40), a top panel (42) and pair of side panels (44). Each panel includes its own light guiding groove arrangement of a SCOTCHTMoptical lighting film (SOLF) (50, 70, 88, 108, 126, 146, 160) and whole portions or segments of a light extractor film (84, 98, 104, 136, 156, 158) for either directing the light from a fluorescent bulb (48) along the SOLF light guides or into patterns of light onto and through transparency (50). The SOLF grooves transmit the light in the direction of double headed arrows (78) in bottom lens panel (40) toward side panels (44), which direct the light as shown by double headed arrows (96). The grooves in top panel (42), as portrayed by double headed arrow lines (116) guide the light in a wrapped arround manner between front and back panels (36, 38). Grooves (132, 152, 64) in respective back panels (38a, , 38b) and in front panel (36) extend between top panel (42) and bottom lens panel (40). Grooves (76) in bottom lens panel (40) direct light parrallel to the axis of the flourescent bulb (46) while all other grooves, including light wrap-around grooves (114) in top panel (42), direct light perpendicular to the bulb axis.
