The speeder shot is probably never going to look much better than Harmy has done with it, but if it proves the most popular, I’ll do it.
If the purpose of the demonstration is to show the strengths of the software you have developed, I would suggest also picking a sequence where you expect the maximum benefit of the software.
With regards to the speeder shot, I’m curious to know the maximum image quality that can be pulled from the prints, without reverting to the in my opinion somewhat revisionist techniques employed by Mike Verta to clean up the speeder shot, and essentially remove all the color noise that most likely also existed on the original negative. The downside of removing all the color noise in my view is, that you will never recover the detail that should be associated with such a clean image, and thus the cleaned up image may actually appear less natural without the noise than the image with the color noise in it. In essence when our eyes cannot see detail, we expect noise. If we detect neither something is amiss, and we get that heavy DNR effect. So, I believe noise reduction should always be in the service of detail recovery/enhancement, but not be a goal in of itself.
