You clearly never worked at Complete Post. The Engineering department frequently would use the TAF just to see if there was "a picture" there, to run through alignment of the Ranks or Spirits and make sure there were no alignment or maintenance issues. For real world pictures? No way. Not even close. We had 8 Ranks of different vintages at one time, and over the years eventually upgraded to 11 Spirits (some HD, some 2K, some 4K), None of them could reliably make usable pictures from a client's negative based on the TAF. Maybe we have different ideas about what "usable pictures" were. All I did was simply have the DP shoot a reasonable grayscale chart on the first day and then I saved that correction in a memory. Generally, that would be a vague starting point for PECs, negative gains, and all that other stuff. In truth, some of the worst film scans I've ever gotten were those made from test films. I've had my share of (polite) screaming matches at Cinesite, ILM, and Technicolor from low-level staff people who would blithely set up a scan according to some phantom procedure, and then blindly scan a piece of film and never bother to look at it. If I complained and said, "the blue channel is 50% low!", their answer would be, "well, the test film looked fine." Eventually, I got the scanning & recording guys (I almost just used a more colorful word, but decided to be polite) to realize that every piece of film was different, every project was different, and they'd have to use good judgement to scan the material to get that specific project within reasonable range for whites and blacks. Once I demonstrated to them it only added about 5 minutes to their setup, they very reluctantly agreed to do it my way. It cut hours off my setup time, just because we were starting with a balanced scan. We now return you to our Alexa thread. Again, I really like the Alexa, I think there are a lot of good things about the camera, but the later Red cameras (starting with Dragon) made a lot of progress, and I'm liking what I see so far with Weapon and Helium. It all really depends on lenses, lighting, and exposure, and if you're optimized on all three, these cameras can make perfectly fine pictures.
