The Holga is an inexpensive, medium format 120 film toy camera, made in China, appreciated for its low-fidelity aesthetic.
The Holga’s cheap construction and simple meniscus lens often yields pictures that display vignetting, blur, light leaks, and other distortions. The camera’s quality problems have become a virtue among some photographers, with Holga photos winning awards and competitions in art and news photography.
Similar to polaroids, pictures taken with a Holga are called holgaroids.
