Profoto 100991 Umbrella Diffuser Med 1.5 Stops

The Profoto Umbrella Diffuser (Medium) is a simple accessory that is pulled over the front of a white or silver umbrella to turn it into a medium-sized softbox, thereby creating a softer and more diffused light. Compatible with the Umbrella Shallow White M and the Umbrella Shallow Silver M, this diffuser reduces the output by 1.5 stops.
