Travel photographers concerned about this problem (a fairly serious one at times) might want to look at POPULAR PHOTOGRAPHY, May, 2002, pages 28-34, for a full discussion of the matter. There are no easy answers for this problem, made much more complicated since 9/11/01. Hebert Keppler won't set your mind at ease, but he does define the problem quite well. Cheers, Bill in Baltimore
