wrong "Max Aperture Value" #15

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Example image: 
http://www.aperturaphoto.com/blog/wp-content/uploads/2011/03/Apertura_erwin_Anas
tasia_Las_Vegas_Portrait_009.jpg

What is the expected output? What do you see instead?
There is no lens with 0.625 max aperture. This lens is the Canon 50mm/f1.2, so 
the right value is 1.2.
For example the FastStone Image Viewer and this FireFox Add-on 
((http://araskin.webs.com/exif/exif.html)) is almost good (They show 1.24. Not 
perfect, but much closer :-)

What version of the product are you using? On what operating system?
1.3.4, Windows 7

Please provide any additional information below.
The above mentioned sample image is attached, just in case.

Hmmm, this is really odd cuz this value in windows photo viewer and few other 
apps that show exif is also 0.625 
(http://dl.dropbox.com/u/39474356/exif/max-aperture-bug.PNG);
I parse the EXIF section according to EXIF format specs and have no idea why 
max ap value has been broken in that case...
