The ColorCorrect tool v2.0 will be released later today. Apart from the improved color matching capabilities of the algorithm, the new algorithm has a very much improved stabilization option, that allows for very good color matching, even if the source is noisy, or if the colors of the reference has inconsistencies. Here´s an example of matching the Star Wars bluray to a problematic frame of the technicolor IB reference print, with ColorCorrect v1.4, and ColorCorrect v2.0:

I think the '97 is clearly an uncorrected scan.

I hope that’s the case!

Are the most recent 35mm IB sources corrected? They look much better than others.

Nope it’s the same scans, but they do look very good, aside from a slight pink shift in the highlights.

It’s colors do look a bit funky, especially the Tantive IV ones.

It’s interesting to note the color differences between the Tantive IV scenes on the bluray, the 1997 SE print, and the 1977 Technicolor IB print.

Where did you get those? Did I miss something?

Team -1 posted a few preview frames here a while ago:

Here’s a couple more examples of regrading the Star Wars bluray, using the 35 mm print scans of the 1997 SE of team negative1 as a reference.

It looks awesome! Great work!

Here’s a comparison between the bluray, the bluray matched to the Technicolor IB print, and the regrade based on the latter, with manual adjustments.

Yup, these are just color matching tests. A proper color timing would probably have somewhat less contrast, and saturation, which is what I suspect Harmy and camroncamera are doing at this very moment. The soldier and Vader frames from a few posts back are my personal attempts at properly color timing the bluray, by color matching the bluray to the Tech with the software, and then manually adjusting them to the desired final result. I showed them to Mike Verta, to get his opinion on them, and he thought they looked good.

Yes, prints tend to have more contrast, than the interpostive on which they are made. Blurays releases are usually based on a scan of the negative or an interpositive if they want to keep the original color timing. Prints get more contrasty with each generation, which can be seen on 16 mm prints, that are usually based on scanning a 35 mm print. The result is more black crush, and blowout.

Here are another set of frames of the bluray, that have been matched to Technicolor IB print references with the new color matching engine.

The color correction tool v2.0 will be released soon, which includes a better color matching model. Here’s an example of matching the lobster frame to a Technicolor IB print reference:

Thanks! Here’s a slight adjustment of the regrade, because the color matching algorithm (I use Technicolor print references, with some manual adjustments) was set with too much stabilization, resulting in dim blues:

Here’s another attempt at regrading of one the lobster shot. The artifacts are reduced, but since they’re also present in the shadows of the source, it cannot be completely removed. Aside from the correcting the unnatural skin tones, R2D2’s blue panels are really screwed up in the bluray:

Yes, this is a difficult one, that requires some more work.

Just used this tool for the first time today. Wow! Thanks, DrDre!

You’re welcome!

Yours looks pretty spot on to me. I’ll be going back over the first two reels before I’m done, so I don’t have a final image yet, but it may have a touch more blue in the uniforms.

I think you’re right. Here I added a touch more blue:

I’m kind of curious what grading you’ve given the rebel soldier shot? Here’s my version:
