I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.
If you are looking for a Perl tutorial or Perl-related news, I hope these links will serve you well.

FocalLengthIn35mmFormat vs FocalLength35efl

I can not believe this: I just bought a $200 FUJI camera for a family member and it does not set the focal length value in 35mm terms! I thought these days every camera does that. Yikes.
Anyway, as I was studying the EXIF data I noticed that this information is in there somehow.
What I have:

[ExifIFD] FocalLength: 5.0mm [Composite] FocalLength35efl: 5.0mm (35mm equivalent: 29.0mm)

Now, how is that FocalLength35efl computed? With some string processing I could get out the required numbers and put them into FocalLengthIn35mmFormat. That way, one does not have to remember the conversion factors for the various sensors.
Thanks for any info, Mixx
