Color matching and prediction: color correction tool v1.3 released!
Time

Just to throw a monkey wrench into all of this, I have personally noticed in the past that tinypic changes the color of images posted there.  I know this because I was using it when posting screenshots from my 35mm trailer project and the color was off after uploading.  I don't know if they fixed this issue, but I don't trust tinypic to be represenative of the colors that were uploaded.

With that being said, the latest DrDre picture doesn't have white storm troopers.  I think I like the Harmy regrade the best at the bottom of post 338 or the DrDre one right above it.

Color matching and prediction: color correction tool v1.3 released!

Ronster raises a point that I have been thinking about too.  What it looked like in theaters and what it looks like in real life or what the intention of the look was supposed to be are often two different things.  It's almost like there needs to be two versions of color fixing for a film.  One is to make it look like it did in the theater (good or bad as it was), and the other is to make it look correct as if it happened right in front of you.  I hate all of the orange and teal they are doing these days.  Yes, that is what it looks like in the new Star Wars trailers (orange and teal in at least the first one that came out), but looking at the trading cards in comparison which have the original colors, I much prefer the look of the trading cards.

at 44 seconds.  His suit is fluffy baby pink blanket instead of orange, and where did his 5 o'clock shadow go?

My personal vote is to make it look correct in terms of skin color, flag color, etc. taking into account the lighting that affects this.

CatBus's comment is cool too.  This can get into another issue where HDR would be required in order to have all of the color properly.  To keep all of the detail and both the high and low end, the colors need to be "compressed" into the Rec.709 colorspace which is a small subset of the real world visible color range.  Your eyes deal with the wide range by opening and closing the iris. When you are outside on a bright sunny day and walk into a relatively dark room, you can hardly see any thing (sort of like black crush).  After your eyes adjust, you can see a lot better.  If someone filmed from inside the room and there was a window that could see the outside, most likely the window would have mostly white blown out details.  If they then went outside and filmed a scene with a window to the inside, it would be mostly black. This is because the camera has an iris too.  If the camera was HDR capable, it would most likely preserve more of the details and on an HDR display they could be shown properly.

Also other factors play into it.  The bulb in the projector degrades over time and will produce a different look as it is projected.  Scanning a 35mm film doesn't mean the result is what it looked like.  I know this first hand from my trailer scanning project.  You need to scan at different settings with multiple scans to capture all of the dynamic range.  Any one of those scans looks different than the others, so which is correct?

Lots of rambling, but in the end, my take is that the color correction should strive to reproduce the lighting and color of the scene as it looked in the real world as much as possible, unless they purposely altered the look of a particular scene to add more atmosphere to it such as for a scary movie.

Oh I'm not arguing that it wasn't worth it, I'm just saying using a 35mm source to remove halos just kind of defeats the purpose of this project.

 I disagree potentially.  I think it is a brilliant concept if it actually works.  From my understanding it would only take one frame to figure out the math formula that could be then applied to all of the other frames that would remove the halos.

Edit: V12 is still my choice, like FrankT said, the haloing is too distracting.

 I don't think the haloing is affected in V12.  It is there in all versions.  I assume you are saying V12 is your favorite because of the better anti-aliasing.  I think V11 is better because it has a bit of extra detail and the anti-aliasing is good enough.  Maybe we can get the scripts and we can make our own versions.  :-)

Examples of what it would be if the color correction was applied at about 38% or so:

http://screenshotcomparison.com/comparison/142150

 Those look really great!  In my opinion, that approach gives a better / more pleasing end result than the raw versions that are overblown a bit on both ends.  I would take it just a touch further though to be closer to Dr Dre's but not too much further. 

Regarding V14, it's hard for me to judge 100% on the screen I am using because it is my color calibrated plasma TV which is great for color but not perfect for fine details.  However, I think V11 is still my favorite.  This screenshot for example seems to have a more pleasing look:  http://screenshotcomparison.com/comparison/130594

I found the same shot in V14 and most of the grain is gone making it look a bit less natural and at least having the illusion of less detail although there is probably the same amount roughly.  If I could have my way, I would just go with V11 and it would be interesting to see it with the not overblown but much more accurate color corrections using the method proposed by Cutedge.

Here is the short clip of V11 for comparison: https://drive.google.com/file/d/0B8_LYKyZDiajam0wVHZRblFrVjA/view?usp=sharing

Thanks DrDre for all of your great and hard work!

On a semi-related note, I did an interview for the Undressing Undergound podcast, in which I talk about Legacy a touch, along with a salad-bar of various other topics.  This is the same show that had TV's Frink on, once, which should give you a pretty good idea of what to expect.

Sounds cool! The link doesn't work for me.  Does it need anything special to watch it?

It seems slightly less detailed than before, but overall it seems to have the least jarring issues when watching it compared to previous versions.  I feel like I can just watch this one and enjoy it whereas with the other versions, stuff pops out that distracts me from the movie from time to time.  It would be cool to see your new V12 to have something to compare it to.  Great job!
