Alfred Stieglitz's *Selected Lantern Slides* showcases the pioneering photographer's mastery of light, shadow, and composition through a series of glass-based photographic transparencies intended for projection. The works reflect Stieglitz's commitment to elevating photography as a fine art, capturing subjects with a painterly sensitivity that blurs the line between documentation and artistic expression. Together, the slides offer an intimate glimpse into his evolving vision and his dedication to transforming the photographic medium into a vehicle for deep aesthetic meaning.
