Just curious what your thoughts are on the possibilty of a nighttime picture with children. I have seen one setting in particular that I really like where the kids are gazing at a lit string of Christmas lights. I have a Nikon D40 and really want to learn to use it well. I do have a tripod, which I know will be essential for the slow shutter speed required at night. But is it possible to have my subject (4 kids) not be blurry? I've been reading the manual, but am thinking that people with experience might be a better source of info for me. Thank you in advance.
