Re: [Openexr-devel] EXIF meta data attributes in headers

[Piotr Stanczyk]

Hi Florian,

As you point out, the optional standard attributes contain iso,  
exposure time attributes ... I was thinking about whether it would be  
suitable to encapsulate the entire EXIF structure in a single attribute

I was prompted to think about this when noticing that we occasionally  
read in digital camera source images as OpenEXR files into shake, do  
some light processing and write out Jpeg & Tiff files out of shake  
that need to have the Exif data in place.
The current implementation writes out the tags that we want in the  
Exif output file one-by-one. This works fine, but I was wandering if  
its worth keeping the data in the pipeline....
