I made the comment on the old jedi.net forums, but Cineform HD avi is a great mezzanine format. This is a segment of Temple of Doom:

It's now free for home use:

Limited to 4:2:0 colour space, but definitely worth considering. We use the pro version at work to ingest from HDCAM SR.

This is very much a viable option - I wouldn't know where to start working with OpenEXR.
we have had terrible problems looking into cineform.
no way we would use that... then again, we haven't
tested openEXR either.
so basically you have to choose your poison.

there are so many propietary formats used
by companys for their high end software,
that are kind of standards.. but not really.
if you stick with one software suite,
you want all your tools to work together.
uncompressed TIFFS are huge. jpgs don't
support some of the high end formats.
every filetype format has its pluses and minuses.
