Chip Chart On Set

Hello.

Do any of you use a chip chart on set for narrative productions? And if so, can you give me an example of how you would use it, from production through to post? Are there any good resources I can research on the topic? Sorry if the questions seem a big vague. Most of my work requires baking a look right into the footage with very little color work in post. I'd like to dig more into Resolve and I'm thinking a chart on set would probably go a long way to simplifying the process.


Thank you.

A chart as reference is always ideal to have for color correction in post, but if you're careful to white balance as needed when recording and you're not shooting in log or raw mode, you can dial the camera settings in exactly the way you want them in rec709. Just make sure you're not clipping highlights when recording and you should be ok especially if you're recording at least 10 bits per channel color.
 
Thank you Chris. I almost always shoot Slog 2/3 and sometimes RAW. Rarely do I bake in a look. I may have to pick up a chart and play with Resolve to see if I can get any use out of it.

I always try to do a color chart either for every scene, or ideally for every different light set-up.

I find it helpful to have as a way to counter your eyes adjusting to certain colors in the color suite. There are steps you can take to keep your eyes from adjusting, such as taking breaks. But still, I always try to shoot a color chard before slating on a new set-up.
 
What are you editing with?

As for how it's used; throw Three Way Color Corrector on a clip and use the eye droppers for the three ranges on your chart (white, gray, black). That gets you to neutral color based on the chart standard. Whatever you do after that is more independent of the chart reference.
 
Last year Adam Wilt produced a nice webinar on using test charts.

Here's a follow-up article he wrote that includes a link to the webinar and other useful background info.

Looks like the webinar is now behind a paywall, but there's a free 14-day trial:

We use charts on some productions. Useful tools for ensuring consistency, especially if you're working with different cameras on the day, or shooting on different days. Tends to be DSC Labs ChromaDuMonde on higher-end productions, and DSC Labs OneShot on quicker refined-gorilla jobs.

But they sure aren't on every job I'm on or even every job I'm driving.
