If the time setting is longer than it seems practical, try to get more light on the card / hand.
dr bob, I think that Annie was asking about a 1/2 second pre-exposure followed by a second exposure which her meter indicated as being 4 seconds. Perhaps I am failing to understand your answer but it seems that you are answering on the basis of only a 1/2 second exposure . Please straighten me out if I failed to understand you.
