Having taken so long over Mod 1 I was keen to get on with getting Mod 2 ready whilst waiting for Mod 1 comments. I have run the grey card test a dozen or so times over last two days (yesterday in shade, today overcast) with similar results. The "correct" (i.e at 1/60 sec) exposure, instead of measuring 128/128/128, repeatedly came out at around 158 or so. I tried different ISO and White Balance settings with similar results. I therefore tried building in exposure compensation of -1/3 and -2/3 stop and found I was able to get readings in the 128 range for the 1/60 sec exposure. I am using a new Nikon D300 and had thought my pics were a little overexposed occasionally so I do not know whether it is my ineptitude or a feature of the camera settings in certain circumstances. I am now concerned with what to submit for Mod 2 . Any comments anyone or any view Garry?

We have found that manufacturers regularly calibrate their cameras so that a mid tone is recorded with a brightness value of something other than 128. It doesn't mean your camera is faulty, it is how it is set-up. Making mid tones darker than they should be by underexposure, for example, will help retain highlight detail.
