Incorrect exposure bias value

[Anasthase]

Hello,

Attached are 2 files with non-zero exposure bias value. DSC_5644 is +0.3 EV and DSC02268 is -1.3EV. Easyexif reports 0 for both images.

In fact the exposure bias value is not read at all, as the expected format is 5, but the reported format is 10. I've tried to force-read the tag as format 5, but it crashed.

Thanks for your help.

This is because ExposureBiasValue (or ExposureCompensation) is a signed rational which isn't handled properly.

A signed rational is format 10 and this code only handles formats 1-5.

Because of this, ShutterSpeedValue and ExposureBiasValue will not be correctly reported.

FYI this repo isn't updated anymore.

If you look at my commit (just above your comment) from 2018 to my fork , this issue is fixed along with another one. (I also fixed other things and updated the code.)
