I tried to start working on the lightsabers myself ages ago but with work and family never had the time to finish what I started.
After spending weeks working on this I know how hard it can be to work around the original effect and I'm very impressed with the quality you managed to get. Even better is the fact that you managed to get them to look more like the blue OT lightsbaer colours than going the way of the PT which was leaning more towards a blue-violet colour range.
However I did notice that the core doesn't seem to have quite the right whiteness to it as the OT had originally, also Vader's saber appears to be a bit too Strawberry Red. Just wanted to give some constructive advice as I want you to produce the best you can and get the pat on the back you deserve for doing this.
I'm curious as to how you managed to get such great shots. For example in the falcon when Luke begins to use the training remote and we have the wide shot I created a clean back plate from when he finishes and walks over to Obi-Wan as he sits down after sensesing a disturbance in the force.
From that I then rotoscoped Luke into the clean plate and then removed his lightsaber blade which as you all know tends to jump around and shift angle independently of the angle it is being held. I then put in a thin red blade to check the new angle of the blade and then used that to create the new lightsaber blade over the top.
Very tricky to get the right motion and still stay with the angle of the lightsaber in Luke's hand. Another problem I had was Chewbacca sitting down in the background. By removing the original blade I had two problems, one was that the old blade was on his head and didn't match the angle of the new blade so you would still see it, two was the glow from the balde was green and not blue which also was on top of him.
I managed to get clean frames of Chewie and rotoscoped him in and then have him go forward as normal and then before the lightsaber moves onto him reverse the footage back the way. At first I had him just be still but thought that was cheating so I did it this way so he still moves.
Just a query will you be sorting out any garbage matts?
