Some digicams bump up the ISO thus allowing faster shutter
speeds to capture an image in low light conditions. Posting
pictures of night shots here does that well when no 'blurring' is
shown and you crop your images or skew them down. That's why they
look good. View them in original full size and pixel i say most of
them CMI! Unless you are using a DSLR that handles higher ISO shots
in low light conditions better than the normal digital cams, the
only best options available is to use a cam with both true
'anti-shake' (that only improve by a few stops) and
'shake-reduction' (that selects an appropriate highest ISO) or
simply use a quick setup convenient tripod.
