Alex,
I use this Bris with a digital camera. The reflected image isn't as bright as direct sunlight. At extremely low altitudes near sunset no sunglasses are need when the Sun is an orange ball. At higher altitudes with a different Bris then sun filters need to be added to the device. On the camera there is some flexibility with the exposure settings and in the electronic dark room.
