First off, when trying to find the original look, there are some big clues and some sources that we have that are pretty good. First off is the technicolor print.
He’s going to stop reading right there because he “doesn’t trust prints” and wants to figure out “how it was meant to look” and not “how it actually looked.” In other words, an excuse for him to make horribly inaccurate “corrections” and then say “But I think that’s how it should look!” when someone tries to give him any amount of constructive criticism or advice.
Oh, and he’ll still refuse to calibrate his monitor, so every correction he makes will continue to have zero value to anyone but himself.
Well, that is what accurate color photos of costumes are for. I posted those as well and met with similar responses.
Such as these:
And that doesn’t even begin to get into how the sets were lit and how it was processed. I don’t think any of the extant copies are exact, but I think if you put all the pieces together, you end up with something close. That is why I point out that DrDre and I have almost the same results with completely different methods. And if you want to go a step further you could try to get in touch with the costumer designers or those who care for the costumes today for Lucasfilm, and see if you can pin down the exact fabric and color used and get samples of it (if they still make it). But that is going a bit far when there are such good resources already available.
