Hey Jason

were approaching the final grading of our feature "2Flags" shot last summer on the Mini SI.

when we did the film out tests last year (at Fotokem) we had to create our own LUT files since none where available then.

I was wondering if you can (slowly please, and with as little numbers as possible :)
tell me what has evolved since last year in tearms of available LUT's for different film sotcks, Labs that may have already handled cineform RAW footage, and some suggestions on calibrating monitors (apple cinema displays)

we could Pmail about it but I thought that the other members of the thread might profit from the discussion

Thanks

Lior

Hi Lior,

Overall we have only provided a generic 2383 visualization LUT that can give you an "idea" of what the footage shot by the camera will look like when filmed-out to Kodak Vision print stock. It is not really a substitute per-se for a more accurate LUT from Fotokem.

The "film-looks" that are on the website are actually a bit different, in that they redupilcate the look of Kodak original color negative film stock, and map the color-space of the camera to those stocks so that the camera really "looks" like film . . . they are not the same as taking the native color-space of the camera and visualizing the end result on a film-out which is what our "Netural_2383.look" file is for, albeit in more generic sense for generic sRGB monitors.

One thing to keep in mind Lior is that many of the LUT's out there are expecting files that have a Cineon input curve. We provide a .look file that makes the files from the camera conform to the Cineon spec. If you use our normal LOG curve from the camera, which is not Cineon spec, your files on the film-out will typically look very dark with highly crushed shadows. This is because we do not set the black-point at 95 like the Cineon spec, but at a code value of 2.5 in 10-bit space. So when you simply take our files and apply a film-LUT visualization curve to them, you get a really dark black picture because all the values below 95 get clipped off.

The "Neutral_2383.look" file first maps the camera to Cineon color-space before it passes it through the film-print emulation LUT, so you get a proper vizualization of what a film-out will look like, but you need to keep in mind that fact that it is assuming Cineon input. If you simply then take the RAW 10-bit LOG from the camera which is not as "bright" as Cineon, you will get very dark files when you apply the same print visualization curve in post.

Thanks,

Jason
