Hello
I am testing an albumen silver bromide emulsion to make Lippmann plates.
Here is the result, although faint there are some fringes!!!

Cool.
I seem to remember that in his journals Neuhauss pointed out that he had experienced difficulties obtaining high quality photos with albumin. Perhaps excessive grain growth is an issue.

Wow, Thanks!
It was very insensitive to the 488nm laser, even 10 minutes didn't give great results, but I am using Pyro-ammonia developer, that might not be too suitable, I only have experience in DCG holography, this I did to test the feasability of making Lippmann plates using albumen, which I was able to do yesterday!
A friend just told me that this can't be called an emulsion as I coat the plates with unsensitized albumen and sensitize afterwords...
here are the sucessfull panchromatic Lippmann plates I made:
