Color correction with Color Checkers in 3D LUT Creator part 2

[@KevinJackson1]

You are seriously a color genius!

[@DaveDugdaleColorado]

Nice! I can't wait to try this!

[@ookiemand]

Help to match up camera's, and get some nice colours! - looking forward on your review of this.

At 3:19 you show a list on the left (Gray, Exact, Color, Hue, Sat, Lum) that doesn't appear in the version of 3DL I bought this weekend.

You can do it by using "curve" matching method. Place the color grid over the color checker in the image and select the curve matching method. They just minimized all the steps into one click.

Is it necessary to have the x-rite colorchecker for this to work? What if I have a chart (or make one) that is not supported ?

[@aaronperelmuter8433]

Of course it necessary. How could it possibly work with any other chart when the application would quite obviously have no clue whatsoever as to what colours are in your chart, let alone what the colours ideally should be. Did you actually watch the video? The whole thing is about correcting the colour cast and this is ONLY possible because 3D LUT Creator knows what the colours in a ColorChecker chart are supposed to look like. Otherwise, you might have fluorescent pink for the red patch, fluorescent green for the green patch, etc? You could have literally ANY colours you want in your own chart which you created but that’s completely pointless because the app wouldn’t know that you’re using your own, wacky version of a ColorChecker instead of the Xrite version, as per everyone else. Moreover, why would you ever even want to create your own ColorChecker chart? It’s been the reference standard for, maybe, 40 years or so now, do you not think there must be a very good reason for that? Does it not occur to you that for SO many photographers, worldwide to all use the same chart, over several decades, that just maybe there’s something worthwhile in the colours from said chart or perhaps the colour combinations from that chart? Just some food for thought is all.

⁠@@aaronperelmuter8433no, the workflow shown here can actually be applied to some very effective color correction. As long as his chart has a decent amount of gray patches, he can match to any color from his chart as he wanted. It may not be as color accurate as using a color checker, but it would still be a lot better than the original.

I so much want and need this to work but I find it ludicrously difficult to fathom. I want to take an image of the colour checker chart and get this tool to give me a LUT to correct the image to the correct reference values for all patches. Can this not be automated - or made simpler. Or is there anywhere that explains this simple task more clearly?

[@agorka]

Hello! Send me your footage and maybe I'll make a video with it, showing how to do that.

[@bulut6759]

hello, I bought 3d Lut Creator Pro couple days ago and I don't have linearize button on the right side. The UI is a little bit different. where is it in the new version? couldn't find it

[@agorka]

Hello! Thanks for the purchase! Now it is called Curves method matching, you can choose it in method drop down list and click match.

если превратить бледный видео файл slog 2 с sony a7s в jpeg то вся информация цвета теряется...было-бы просто супер если-бы была поддержка корректировки видео файлов...

[@agorka]

licor Так весь смысл LUT'ов и заключается в том, что их можно накладывать в других программах. Кадр из видео нужен только для того, чтобы накрутить сам LUT, после чего этот LUT можно загрузить в Adobe Photoshop, After Effects, Premiere, Davinci Resolve, Avid, Nuke, Houdini, Scratch и много еще куда. Конечно кадр из видео лучше сохранять в TIFF, чтоб не увеличивать артефакты, но даже в JPEG если плашки сняты достаточно крупно, информации будет достаточно.

[@ttimson]

Oleg Sharonov Ну я вчера таким способом и делал корректировку из tif. файла (загрузил slog 2 видео в фотошоп ) Но артефактов достаточно много получилось, я наверное слишком сильно всего накрутил. Буду ещё пробывать - программа конечно очень крутая!

[@ttimson]

licor Кстати советую вот этому америкосу под моим комментом ответить )) у него один из самых крупных блогов именно по видео, видно что он тестит вашу прогу.
