just for a slightly registered, histogram matched version of that comparison:

Jesus, that’s a huge improvement - how did you do it? If there’s something I still feel like I have A LOT to learn about, then it’s color correction - would this be possible to replicate in AE?
Here’s what the raw scan looks like:

and what you see in the BD vs LPP comparison is the best I was able to get out of it.

I completely missed your reply - Honestly, I have no idea how to replicate it in AE. As strange as it seems, I find I get the best results in GIMP. It has a very simple image registration tool you can add, as well as the histogram matching script.

-Image Registration Plugin: http://registry.gimp.org/node/24248
-Histogram Matching: http://www.silent9.com/blog/archives/162-Gimp-Script-Histogram-Match.html

(I’m working on an example using the raw scan, but my work computer isn’t very fast with image registation.)

Since I’m unsure how to do this in AE, my suggestion is to histogram match in GIMP, then use DrDre’s Color Correct tool to build a profile between your source image and your histogram matched one. I find that Dre’s tool works great so long as the image is cropped perfectly, so finding a color correction you like before hand and adjusting to it using the tool provides a pixel perfect adjustment match that’s more easily applied without getting artifacts.

GIMPs image registration isn’t the greatest, and I don’t know how to automate it between two sets of pictures. Because of that, I tend to use it more to adjust pictures for comparison images.

With histogram matching, I’ve found this process works best for me -

  1. Open both images in GIMP (seperately not as layers)
  2. Using LAB (preserve Luma) Match your reference image to your Source.
  3. Using RGB, match your source to the reference image.
  4. In the Reference image window, edit>undo Match Histogram
  5. Using RGB, again match your source to the reference image.
