Re: Colour, Colour, Colour.

I didn't mean actual "rooms", but a grouping set of grading corrections.

I think there's a bit more on that type of workflow here:
http://usa.autodesk.com/flame/featur...olor%20Grading

in the book, the tools he uses may not be providing sufficient control
he mostly shows corrections based on dark/mid/highlight corrections, but it looks it will be difficult or I didn't see it done in conjunction with hue range for example or/and saturation level/masks.
(again.. I didn't have time to read everything and I took just a quick look through the book)

Re: Colour, Colour, Colour.

ok, I found it in Chapter 4
and this is where it gets interesting!

however... saying that the complementary to blue is yellow...
I couldn't disagree more ... but in any case, the book is a must read

Thanks again for pointing it out.

Yeah, learning to make luminance and color based qualifications was a big turning point for me. This has a huge carry over into working with still images, too.

As far as the "complimentary" colors thing, I agree with you. The proper term is opponent colors, not complimentary. The video color wheel is different than the standard color wheel and is based on the red green and blue primaries being equidistant. In video land blue and yellow are exactly opposite each other instead of blue and orange. To quote Andy Tanenbaum, "The nice thing about standards is that you have so many to choose from."

Re: Colour, Colour, Colour.

As I stated but got laughed at here before, color grading is all about the knowledge of color wheel. IMHO one needs to study the way that things are done traditionally. For example, the following book can give you a good start.

Re: Colour, Colour, Colour.

mshi, that looks interesting. I may pick it up for my ever ballooning library!

When it's in print and reasonably priced I also recommend The Art of Color by Johannes Itten.

For reference:
http://www.amazon.com/The-Art-Color-...1910286&sr=8-1

Currently $2k used on Amazon which is ludicrous. I picked it up a few years back for a much more reasonable $90. It's a hard bound coffe table sized book and the printing quality is exceptional so the price is justified.

The colour wheel giving proper complementary colours is not in any compositing or grading software (at least I haven't seen it in any) and is used for aesthetic decisions only (achieving colour contrast, etc)

using a "colour wheel" for corrections usually means that you simply specify hue/sat shifts, which will be making global corrections. You may have 3 or more separate wheels, to make the changes in darks/midtones/highlights separately.

however those corrections will still affect all hues for a given lum equally, so to get things more "creative" you'll need some additional... targeting/masking

Re: Colour, Colour, Colour.

There are more than one version of color wheel. Newton's discover of light spectrum expressed in HSL gave us his seven-color version, while Goethe not only gave us his six-color wheel version but emotional meanings of color as well. I don't want to bore you with the rest. When some say color wheel is irreverent in today's screen world, I would argue otherwise.

Just found a vid for a brief intro to the subject on Google. Forward to 4:40.

Natalia Taffarel (or I think she's known as Godmother on this forum? correct me if 'm wrong about the nickname), in my personal opinion is a mediocre retoucher, but amazing self-promoter!
(hence a lot of people on forums take her word as a gold coin)

Unfortunately not all can distinguish fact from imagination...
and that colour-wheel that she shows in "her's colour theory" is a very good example.

As in no chance in hell in any version of the actual colour theory, Green's complement colour is Pink nor Red's complement is Cyan as shown in her colour wheel example!

taken from her page, quote: "Knowledge in Color Theory can give you great advantages in the decision making process."

I have to add... but knowing a "bad colour theory" can be a significant disadvantage too.
