View Full Version : Color Correction Secrets
neofg 02-27-2008, 10:45 AM Hi all!
I need a little help with color correction, and I take the occasion to open a thread about GENERAL COLOR CORRECTION TECHNIQUES.
What is the methods that you use for color correction? I never mean the classical cc, where you need to correct whites or adjust midtones. I talk about advanced color correction. [Someone of you corrected minority report or gattaca? :)]
And now my problem: My question is about contrast and warmth... For a lot of time, for fast productions, I used "magic bullet", that I find fantastic. When I work on AE or in Final cut, to obtain a good result I need a lot of time, and is like if the bullet's sliders find the best solution for every images (he,he...obviously)... But since now, I never find something that give me the MagicBullet's results with contrast and warm attributes (and glow too).
Particularly with contrast...If I work with curves, levels, softlight etc...I obtain with a lot of work what I obtain in a click with bullet...
Someone know how it work, (or how work the professionist that never use bullet...he,he)? What is the way to obtain results so "cinematographic"in standard modes?
Answers and links are appreciated!
Thanks all...
Francesco G.

can you believe I entered this forum part because of the same thing?
unfortunately, I can't help you since I'm very very new to this. Every time I see a movie with nice color correction, I wonder how they do those tiny glows and having big blacks too, but a lot of color between without loosing any detail. The things I do usually look very flat. I think that you can have a kinda poor render and make it look very real with just color correction... but I've never done that before anyway.
that magic bullet looks very interesting.
and I see what you wanna get, your reel is very nice, but still hasn't the look of for example the picture you are showing. I'm very curious about that
hope you have luck finding what you are after

If it is a short project I actually use shake for color work....the tools are limitless. I've also come up with a way of seperating all the color channels and recombining them to give me full control over all the colors.

That is a project I colored in shake. There is the final version and a side by side comparison.

My reel has some color techniques on it as well.

That looks cool man. Unfortunatelly I'm using windows.
The screenshot you got from the guy in the ring looks very nice, I think is the one I like most.
I also found that in te Sapphire plugin there is an effect called S_FilmEffect, wich has quite nice controllers there. You should give it a shot neofg.

I did a few video tutorials once to help out some people, to just kind of get them started on the way to understanding creating film looks. Maybe it'll help you, too! :)

What your actually talking about is color grading not really correction. Your talking about generating a look for a film. These looks are all based on photo chemical teqniques such as bleach bypass. I guess what I would suggest would be to take a particular film and try to recreate that look so you can understand what you have to do to achieve this. I take just regular stock videos and redo looks all the time. A good example would be to take a photo of a city and take it into AE or whatever compositor and try to recreate like the matrix look. Take a still from the movie and study it, are the whites really white? Are the blacks really black? What about the over all color tone? Take the time to take your eyedropper and actually examine the pixels. You'll notice that the blacks arent always perfectly black and the whites arent always full white. Also with that you'll notice for example in the matrix for most shots colors lean toward the green side of things. The best tool for doing color grading in a typical package is a three way color corrector, some apps dont have this but they have things that are similar. This lets you play with shadows midtones and highlights seperately. If your looking for glows, in AE you can duplicate your color graded item and place it over top and blur it with gaussain blur. Using a layer mode you can get blown out glows on the highlight typical to camera bloom, be sure to tone it down a bit with opacity. For other applications there are other tools.
Generally in the end there is no one way to do it just try to duplicate what you see and you'll develop and understanding of how and why it works.

Hi all! And thanks for all answers...
I was ill...hemm...
I Can't open vfxtalk...but I appreciated the tutorials on simplycg.
Dear Riktor...Thanks for suggestions...
I work for contrast in AE, and what I do when I color correct contrast is to work with levels and put them over as softlight level...more and more time...
But when I work in finalcut, with 3wayCC, as you said, and I work on single channels, I lost a lot of informations from the image...and that's the real problem! In a classical film look,you can find a lot of particulars in the shadows...But when I color correct with this methods I lost particulars...The way I found better since now is softlight and levels in AE...
:-(
Thanks again...Now things became interesting...
PS.Someone ask examples...I put here frames from Smoking Aces, but Is the same for The Island, CSI or other high saturated, and high contrasted films...
How u obtain that look?

Assimilate Scratch and Autodesk Lustre are some high-end ,ultra powerfull color grading tools,wich are avalable for windows.These two are the main software rivals of daVinci,both were used in prime feature films.
