in reply to Printing hash references for Image::EXIF
See Dereferencing Syntax and/or References Quick Reference.
Where you would do %hash, you do %{$hashref} (curlies optional) like did for keys. Similarly,
where you would do $hash{$key}, you do ${$hashref}{$key} (curlies optional) or $hashref->{$key}.
