I wanted to find out where my camera puts middle grey on the histogram.
I don't have a 18% grey card, but I understand that camera will take the average of the metering and give us middle grey. If we shoot a single color subject, whether it is white or grey or black or any color, it will always come out with the tone of middle grey. And the histogram will show a peak at the center.
Well, not for my camera.
I filled the frame with the blue sky, again the cloud and then the off-white wall. I shot in M mode with spot metering. In all the shots, the peak is about one stop to the left. I have to increase the exposure by one stop to bring the peak to the center.
Have I missed out anything in my experiment or Nikon designed my D40 to underexpose by one stop? :dunno:
