"Meter Note" by Percy Low.

The meter consists of 8 grey tints with cut outs in the centres of each. In use the subject is viewed to see which tint matches the subject. A table then shows the shutter speeds and apertures for the tint. The meter is for Extra Rapid plates only. As the subject is viewed without any intervening filter to remove colours it is nearly impossible to distinguish between grey tint and colour.
