"Producing images of large spaces underground is always difficult, Lighting being the biggest problem. With Meggaflash flashbulbs, not only can you photograph vast areas in a single, softer, warmer flash, you can use slower film with smaller apertures to create sharper images on less grainy film. The photographs featured here were taken in Tunichil Muknal Cave during an expedition to Belize, Central America. All photos were taken on Fuji Provia 100F at around f8." Quote by David Lazenby.
