I'm very late jumping onto the bandwagon of OpenEXR, or the .EXR format for images. My recent conversion to a completely linear workflow has coaxed me into making the jump. I must say however, that I wish I had been using EXR ever since it came out to the public.
For those of you who don't know, EXR is a image format written at Industrial Light and Magic for storing scanned film images or renders. It is a very sophisticated format, allowing you many options for compression, bit depths, and the ability to store high dynamic range values.
I won't go into all the technical information, but just a couple of suggestions I learned.
1.When storing a render without film grain , compress using ZIP lossless compression.
2. When storing a scanned film frame, or digital video with noise, compress using PIZ lossless compression.
For more techinical details on EXR, see these two sites...
The main reason for me posting this entry is this: USE EXR, IT ROCKS.
