The Panavision Genesis camera shoots uncompressed 10-bit HD encoded in a logarithmic color space known as Panalog. Visual effects artists working with these images may want to convert the panalog images to linear floating point and back as a part of their workflow.
At The Orphanage, we’ve always used hard-coded panalog LUTs (based on those supplied by Panavision) for these conversions. But it occurred to me that the format is similar enough to Cineon log that one might be able to find settings in a standard log/lin tool that match the Panavision transform.
Sure enough, a little playing resulted in about 99% success. I got my Cineon log/lin conversions close enough to be within a 10-bit code value of a match to Panavision’s own LUTs.
The After Effects settings are:
10 Bit Black Point: 0
Internal Black Point: 0.0
10 Bit White Point: 681
Internal White Point: 1.0
Highlight Rolloff: 0
The Shake settings are the same, but Shake has a more ‘nuther gamma setting called rNGamma which you should leave at the default of 0.60, and multiplies the rDGamma value internally by 1/1.7, so you should use a value of 1.70/1.480 or 1.14865.
Nuke version coming eventually maybe possibly!
