Please help me understand colour correction.

What I see people doing with colour correction to fan edits to me (who knows nothing of the technical aspects of anything you guys do) doesn't make sense.

I know I'm way off the mark here because otherwise you wouldn't put so much effort in but....can't I just correct the colour using my TV? I adjust colour and brightness etc until I am happy with what I see.

Can someone explain it to me. I'm not referring to changing colour of lasers or lights which are wrong or lightsabers that are wrong I'm talking about the colour correction you put on the whole film.

Cheers

The thing is, when a filmmaker releases a film, he wants it to look a certain way, and he wants everyone to see it the same way.  This is why you should properly calibrate your television/display and then leave it that way.

(Actually, that's not entirely true - you should re-calibrate it every time you sit down to watch something, just in case, but who the hell wants to do that?  I say every few months.)

If you calibrate your display to 601 SMPTE bars, then it will accurately replicate what the director, cinematographer, and colorist intended when they color timed the film, as their displays are calibrated to 601 SMPTE bars as well.

For example, say you pop in Saving Private Ryan, and you think it looks almost black and white.  So you boost the saturation on your TV, and it looks better, like it's in real color, right?

Wrong.  Saving Private Ryan was color timed to be very desaturated intentionally.  That's the way Steven Spielberg meant for you to watch it, so that's how you should watch it, not with the color boosted.  That changes the aesthetic feel of the film, which goes against the filmmakers' intent.

So, the idea is for the color to look consistently good (and the same) on all displays, provided they are calibrated properly.

Unfortunately, the 2004 Star Wars DVDs did not do this, and they still look like utter balls even if your display is properly calibrated.

OK so if my TV is properly calibrated according to this 601 SMPTE bars and the colour looks crap then the fan editor steps in and does the fix.

Me adjusting colour on the TV and brightness is just a personal preference and not what the film maker intended.

I do watch movies that you can see quite clearly have a certain tint or effect to them as they are meant. Like you say Saving Private Ryan, Three Kings, Pitch Black.

So colour correction is against this 601 SMPTE bars standard.

Thanks for clearing it up for me.

Exactly.

If you'd like to calibrate your display properly, the THX Optimode features on many DVDs is a good start, though they're supposedly designed specifically to match whatever film you have put in (I have strong doubts about this, though).

You could use SMPTE bars to set the brightness level, but they're useless for color and tint unless you have a blue filter, or a "Blue Only" setting on your TV.
