Color Charts

I have been using an X-Rite Passport recently because I found my reds were more orange than red on several Sony cams. However, I will need to invest in a larger chart for wide shots.

At this point I wonder if anyone has any feedback about X-Rite Color Checker and Video Checkers vs Datacolor SypderCheckr 24 vs DSC Oneshot.

I am an experienced colorist as well, so very aware that these charts only help to serve as a starting pointing, but it's good to have them to call up when necessary.

I know the DSC Oneshot was designed ground up by Art Adams for Vectorscopes, but manually correcting for that can be very time consuming and I have seen reports that it is not any more accurate than the old trusty X-Rite for things like the Davinci Resolve Color Match.
 
This is timely and relevant for me as well. I'd been leaning toward the X-Rite Passport - waiting for it to be compatible with Resolve (not sure if it is yet). Depending upon the job, I use both Color Finale in FCPX and Resolve - so was hoping to purchase one chart that would work in both applications. But I've read mixed reviews about it...
 
Passport is small, good for close up shots, but for most everything else you would want the Colorchecker Classic which is still pretty small. Both of these are the same tiles, so both should be compatible with Resolve. Not sure if anyone makes a big 11x17 inch version, but we need one that big or larger.
 
One thing I like about the Spyderchekr is that the passport version is quite large and has 48 patches, so it will definitely be more accurate in my opinion.
However, none of these really correspond to REC709 like the Oneshot does.

The X-Rite Video checker (the full size one,not the passport) looks pretty good for balancing in an RGB Parade and Resolve has now included it in color match.

But again, neither of these two will work in photo apps.

Hi
could you please explain why you think the X-Rite Video checker wouldn't work in photo apps?

cheers

Of course you can do some limited balancing manually, but what I am referring to are the apps designed by X-Rite to automatically profile a target.
So both Datacolor Spydercheckr and X-Riote ColorChecker provide stand alone apps as well as working in Lightroom for auto profiling. The big video checker card (not the smaller passport video) is not configured to be read by the photo apps in question.

DSC Labs released a new chart recently, the ChromaMatch. You can pick up the LT version for $238 in a 10"x6" version here: http://dsclabs.com/shop/front-lit-charts/chromamatch-lt/. If you go to their main webpage, they have a 10% off code listed as well (until 4/22).

I found a writeup here: http://photo.it-enquirer.com/2016/02/calibrating-video-colour-reference-chart-chromamatch-pro/ .

I have a Chroma Du Monde chart if you have any questions about that.

Very interesting charts and concepts. Would be nice if Resolve really expanded their charts for Match, including droppers for white, middle gray and black (like Color used to).

This is how I do it manually with my ColorChecker Passport. I have a digital Rec709 version of the color checker, so that I have references on the vectorscope. I'll then align the colors from the footage with the ones from the reference.

The auto match feature in Resolve works okay-ish, but it will come to it's limits if you need to do severe hue corrections. Like when you need to correct S-Gamut on the A7s(1) for 709. Resolve just seems to do color space converions and not individual hue matching.

Curious how the color checker video would compare with the DSC oneshot in your process...

I don't have a oneshot, but I think it should be more accurate. The oneshot only has 6 patches, while the color checker covers much more of the vectorscope.
Oftentimes the major corrections work out fine, but you sometimes want to tweak little things, like placing orange/skin properly, or foliage between yellow and green...
Really depends on the camera and if funky stuff like S-Gamut on the A7s is going on!
