Some people attach pictures of their TVs to prove a point. I was starting to go through Garnoch's Idiot Guide and found some test patterns on YouTube to see how my TV stacks up. So far, I've been looking into clouding, flash lighting and banding. Turns out I had a camera on a tripod for another purpose and thought why not try some test pictures?. I also thought the best way to take these would be in total darkness. I have to focus the camera with a light on and then keep manual focus for the dark. The trouble is I don't know what shutter speed to use. What is an accurate representation of what the human eye sees on an LCD screen? When I have a black TV, looking for clouding, the picture shows nothing at 1/500 or even 1/6. However, when I try a shutter speed of 1 sec. it shows so much clouding that you would want to throw this TV in the garbage! However, the eye does not receive light at 1 sec. shutter speed which represents an accumulation of light (and clouding). I also see some wide banding at 1/60 using a green screen. At this stage, I am more concerned with what I see with my eyes and therefore clouding, flash lighting and banding do not seem to be issues for me. Is there an ideal shutter speed to use in the dark in order to simulate the real problems an LCD might pose, compared to the human eye? I don't want the LCD issues to be confused with issues inherent in capturing the image itself, in the dark. Thanks.
