Many thanks to everyone for sharing information. And how good it is to have a channel like Lowepost, where at any moment a guy like @Mitch Paulson comes in and writes about Sicario and Deakins ... Thanks!

With Aces in Resolve, I usually set the contrast to 0.7 or 0.8 to start with...

Thanks Jussi.

Good morning everyone!

I have a material recordes up on Sony F55 RAW and we are using ACES by determination of the producer.

But when done the IDT (Sony RAW) and ODT (Rec709) everything comes very contrasted and the blues always very saturated. Does anyone know the reasons for this or what to do?

The web has a very limited material on this subject.

My working time:

 

Feature film 90min / 850-1200 shots / grading time ~ 80-120 hours (10-14 days)

TV serials 45-52 min / 350-600 shots / grading time ~ 24-40 hours (3-5 days)

Create Look - 6-12 hours, but maybe 2 hours or 5 days  

regards.

 

Thanks!

some LUTs have applaingly bad maths,

i drop any LUT over a grey scale ramp and look for math errors before using, usualy i re-create in the software to avoid said errors, as they usualy contain math errors.

Good idea man! How do you do those tests using grayscale ramp, can you explain?

You can apply the Log to Rec709 3D LUT from Arri on a node to stretch the contrast instead of doing it manually. You can use that as a base before balancing and doing initial corrections. 

Using a LUT can clip both your blacks and whites, but you can create a node prior to the LUT correction to be able to control that. 

Thanks Emily!

Hello I have a project recorded in Alexa Arriraw (12 bits) to grade in Davinci Resolve. What is the benefit or "sin" of using for example the 3D lut of Arri. Using lut did I lose quality of the material limiting the process of color correction? Another doubt if you use, I must use 3D output or 3D input.

Hi Marcelo. Just curious, how do you feel Bamboo helps you when working with DR? 

Hi, Tom.
I've always worked with tablets, so I feel more comfortable.
And I have a better control over bezier masks for example ...

Hello.
I'm having a problem using Davinci 14 and my Wacom Bamboo.
From the moment I open the Davinci the cursor disappears, being possible to access the software only by the mouse. Someone like the same problem?

I use Windows 10.
Thank you.

My friend Ricardo Herling, Senior Colorist for a long time since before the digital, posted this question on Facebook.
He posted jokingly, because he can no longer see the m31 look applied poorly.

Many colorists, said not to use, others have posted NO LUTS boards ...
BUT, reading the cases here at Lowepost, several colorists say they use luts.

"The film was shot on the Alexa in Raw. We used an LUT to convert the C-Log into P3 color space, which also had a bit of a film emulation baked into it.
Eric Whipp - Mad Max ".

Cinderella was shot on 35mm Kodak film stock using anamorphic lenses. I graded using Blackmagic Resolve through a Kodak print emulation film stock and started by balancing the shots.
Rob Pizzey - Cinderella ".

Whenever this subject comes into play, it seems to be something forbidden, shameful ...
I've heard from producers, "Marcelo, do not use any LUT because the director can see this as something unprofessional" ...

Honestly, I use it when I need it, if I have a material recorded in Arri Alexa in Raw as Eric had in Mad Max, what's the problem of putting Lut from Arri to Rec709 or P3.

If a Faded Look 60s is requested, what's the problem after creating the exposure, skin, light among other correction adjustments, apply a Lut Agfa Vista 400 Expired to visually assist my building of narrative, highlights, and more yellowish averages And slightly greenish shades ... (illustrative example).

What is the problem of applying a Kodak 2383 FilmConvert with grain?

I may be wrong, but I see the facilities and tools for a better job ...

I am against the application without technical and artistic knowledge.
I am against using Blockbuster packages, SuperMan look, Grand Hotel Budapest look, etc ...

I did a test with a take recorded on A7s, see how the same material with the same rating, can get more organic with the CONSCIOUS use of a lut.
See the difference mainly in the skin and shadows ...
* In this series I did not use lut, but could have used ...

It is my vision over this subject.

Hello Paul, thank you to take the initiative in developing solutions for our dear Davinci Resolve.

I need some manual or a simpler explanation of how it works.
Example: ResolveMathxtra.ofx

I did not understand what I should do ...
Could you explain me how to use it?

Thank you!

What is the best player for viewing our color grading works?

I have not yet found a reliable Windows platform player. In Davinci I always have a color and beautiful saturation, in the quicktime is VLC is always more washed.

Thank Tom and Sam for sharing  information.

In a blockbuster film or tv series what is the average time of color correction?

Sometimes I think we run so much due to the term of the channels and producers here in Brazil.

How do you work when you receive a material to create the look?

Talking to a customer the theme skin color appeared.
As I had some free time yesterday I decided to do a test.

I looked for some references and I came on this site:
temptu.com/shade-finder#/intro

I came to some conclusions even if a very basic test and without any obligation to perfection, it is something didactic.

1 - The independent color region of lighter skin tone or darker changes very little, what rules the scope is the luminance and saturation.

2 - Purposely I left the blond hair and green eyes, this way you can also notice that even in black skin tones, the biotype model predominates, and the color of light hair leave the skin with a brighter appearance.

Hello.
I have a question that should be for some as well.
We currently work with various camera types, codecs, and sensor sizes, all of which end up influencing the final file. What process do you have for matching between dji drones for example and cameras like Red, Arri BMCC and F55. I honestly am never happy with the result, it may be perfectionism but it can also be a failure in my work.

Thank you!

So dop was making look in camera so to say ?

This is bad in most cases.

Magnus, I did not get a chance to talk to the DoF.
But if he tried to make this super dark look on the camera, he needs to check if he's in the right profession, he go for a wrong way.

Thanks Margus and Thomas!

The problem with F55 in this job who I working is underexposure in electronic media, it's really complicated. The signal-to-noise ratio is sacrificed. When the aesthetic demands it, it is better to put the noise later. The bit depth does not matter much because the damage comes from the sensor, which when receiving low light sends the noise (sensors are analog devices correct!). I do not have much to do. I'm going to abuse Noise Reduction.

That's my opinion after studying about the F55 and doing some testing.
The ACES dont affect in this case, the problem is a record underexposure...

Hello, I would like to know what you think about using ACES?

I recently started coloring a TV series and Post House decided to use ACES. But I have some doubts about the proper functioning and necessity of it for this project. My monitoring is 10 bits, the material is F55 Raw, but quite underexposed and grainy, I need to have time to do some testing with the ACES color space and the standard REC709.

Thanks Tom Evans!

Hello.
I'm loving the color grading of the Unfortunate Events series but I can not find who's the colorist. Anybody know?

Hello colorists!
I did a study on photochrome and got a look that pleased me a lot.
As I have been testing directly I believe it can reduce the number of nodes.

I started by creating parallel node and applying a general increase in temperature and contrast, then separated layer and sky and grass and made some saturation, hue and curve adjustments. To finish I simulated a kodak super 16mm film and made some more adjustments of contrast, hue and general saturation.

I hope you enjoyed it and that I contributed to the understanding of this look.

Regards!
