Ideally, you want the histogram to peak somewhere between 1/3 to 1/2 way across the display. If it doesn't, then, increase or decrease the shutter speed.
Humayun,
Just wondering why set the camera to 100iso for the test. I usually take all of my Light frames at iso 800 so should I set the camera at 100 or the same as the light frames?

Thanks geoff
