Re: [ApacheGallery] ExifData



If you want it in, check to see if the label we're on is ISOSpeedRating,
if it is, and the Model field =~ /Canon/, then this will print the
ISO, assuming the Image::Info is in $info.

my $iso = (ord(substr($info->{"MakerNote"},182,1)) + 256 *
ord(substr($info->{"MakerNote"},183,1)))."\r\n";

if ($iso == 19)    { print "ISO: 400"; }
elsif ($iso == 18) { print "ISO: 200"; }
elsif ($iso == 17) { print "ISO: 100"; }
elsif ($iso == 16) { print "ISO: 50"; }
elsif ($iso == 15) { print "ISO: Auto"; }


This worked for the G2 sample images off canon's site.

Hope this helps.
