Hi Angus,

We've started using 'fat' EXRs on some projects, mainly as it simplifies
the asset tracking and versioning process.  Our EXR Shake plugin lets
you choose which channels to load (defaulting to RGBA if they are
present).

I expect fat EXRs will become more common - several people here have
expressed a preference for working this way if all the relevant tools
support it.

Ciaran.
