You are not alone here. I posted a similar question a year or two ago. I
also tend to think that there is a lot yet to be discovered in the
photographic imaging realm. I see no reason that we need to be
exclusively focused on historical processes, and driven by the maxim of
"that's just the way it's always been done".
With some effort it seems that some very interesting work could be done
using existing holographic technology. We should also be able to apply
holographic techniques, and modern materials to improve on the old
Lippmann color process too

- Why not apply modern research methods to our testing? One at a time
variable testing for processes with strong variable interaction is
simply not good science!
- Why only limit our scope to old processes or variations on old themes?
- Why only limit our methods to the use of old materials such as gelatin,
and gum?

Yes indeed!

Uh, where exactly is the link?
