About a creative and stylized 3D LUT

[andy cai]

Hi，dear friend

My discussion is about how to create to creative and stylized 3D LUT.

Our film is in the postproduction，the director hope that the final color would be seem a older film（exactly it should be a certain way of printing ）。so first we need to calibrate the projector。it could produce a 3DLUT

now my problem ：

1.Could we simulate the color of older film based on a the calibrated 3DLUT and how to achieve it ？
2.what kind of problems would we encountered when we used the RED materials to simulate Film？

You will benefit most from the services of a colorist who can take the specifics of each scene/clip and develop the right look for it. There just is no "one size fits all" lut. That said, let's can work very well with r3d.

Hi,friend

thank you for your reply

Could you share something simple and basic with us

There is nothing simple and basic that will do this. This is not a LUT requirement; this is a look created with scene-to-scene color-correction software and an experienced colorist.

I've worked with five different LUT generators over the year (including Technicolor's own Luther and Filmlight's Truelight), and to me, those are just display devices designed to simulate what the end result will look like for the audience. The projector merely needs to tell you the truth, not give you something stylized. The style comes through creativity, not through a box.

As one example: Steven Nakamura created the look of 2-strip Technicolor for the movie The Aviator, but most of the work was done through time and skill, not with a LUT box. There were some tricks involved with signal routing and the DaVinci color-corrector used, but it's nothing that can't easily be done with Resolve today.

Hi,Marc

Thank you for your sharings。

“This is not a LUT requirement; this is a look created with scene-to-scene color-correction software”。I didnot understand this sentence perfectly……i think we only need a 3DLUT


"The style" what I said is really an impression or feeling of the films of a certain age。we want to achieve it by a 3DLUT


"most of the work was done through time and skill" .Now assume we have had a calibrated 3DLUT,Could we modify the calibrated 3DLUT and add some parameters achieving" a stylized effect" into it？I only want to know whether it can be achieved by this way！

thank you very much

Hi Andy,
Our programer can create a 3DL LUT for you. Basically it works like this you let your colorist to make a general grade that you like. Then we give you a "cuberainbow frame", you apply the same grade to this frame, from the result we have our proprietary software that renders a 3DL lut (if thats what you use) to run in your projector.
There is some obvious limitations, you can not use gradients, splines, sharpen, or such in this grade as the lut is applied to the whole image as a "flat correction"

"The style" what I said is really an impression or feeling of the films of a certain age... we want to achieve it by a 3DLUT.

You can't do this, because it's source-dependent. As John says above (and my apologies for inadvertently echoing his remarks), this is a creative look that can't be done solely by a LUT. You need a human being to do this, and the look has to be controlled shot by shot. An overall look can get you most of the way there, but much of it depends on lighting, lenses, and exposure.

I'm not the first person to say that in some ways, a color-correction device (like a Resolve, a Baselight, a Lustre, etc.) is an infinitely-variable LUT. But what you're really asking for is a way of creating a desired look, which -- to me -- is not what a LUT is for. I gave you a specific answer where a human being created the look of 1930s 2-strip Technicolor, and also later 1940s 3-strip Technicolor -- with many hours of work and feedback from the director and DP.

The Artist is another fairly recent film where they did a terrific job at creating the look of 1920s nitrate B&W film -- but shooting on color Kodak stock. Again, the LUT only did some of the work; the staff at Duboircolor in France did the lion's share of creating the look.

Hi，dear friend

thank you for your sharings

Your method is very interesting，Could you send me more informations about your method？

1.Could we add some basic sensitivity properties of the films of a certain age into your 3DLUT？

2.The 3D LUT is based on the general grade of certain material，Could the 3DLUT be suitable for all materials

thank you very much

Best is to create a lut that is applied to a balanced redgamma3 / redlogfilm source.

Hi,John
thank you for your sharings

 

[andy cai]

Hi,dear friend

when we created this 3DLUT.Should we consider P3 colorspace or XYZ colorspace???

thank you!!!

up up up up

Is there other idea?

Is there other idea?

Just tell us what look exactly you want or post an example image here.. From a real movie may be..


EDIT: this look like old film to me.. http://www.reduser.net/forum/showth...-an-EPIC-AD-on-an-EPIC-WITH-CANONS-amp-GLASS-!!!!
