Improve Makernote support #8

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
There are a lot of different makernote tags out there.  Here is a great list:

http://gvsoft.homedns.org/exif/

Hand-coding classes for all of these formats may not be the best approach.  
Some analysis could be done to see whether this could be data-driven (say from 
an XML file, for example), either at runtime or design time via codegen.

Another good resource is here:

Please comment here to vote on what types of cameras have extra tags you'd like 
decoded.

Also, adding support for these makernotes is quite easy, and a great place to 
get started if you want to contribute to this library.

Some improvements have been made to the sony makernotes.

Canon makernotes have also been extended, though they are very complex and 
there is still a lot of work that can be done.  This is a great resource for 
them:

Another great resource for makernote data, showing sequences of bytes that may 
be used to determine which format a particular makernote is in.

Support for Sony type 1 makernotes has been improved. This will be included in 
the next version (2.7.0 I expect.)

Olympus makernote directory is broken (Illegally sized directory), but I'm not 
sure whether it's because of the library or the picture itself. How to find out?
