@rodeo_joe1Hi Joe. Not sure this message can get to you, but I would like to comment about the design of my ZLM1 exposure meter. This meter uses a log amp as does your design. It has a linear response to the log of light intensity. The temperature characteristic of the log property is corrected by use of a thermistor. This meter was introduced in 1983. The last one was sold about 1994. Jim Bausch ~ Zalco incorporated.
