Ah, now this makes sense. Reviewing the hologram that I made yesterday, what I'm getting is a faint, grey transmission image and an even fainter rainbow reflection image. This was made with an exposure range of 2 - 12 seconds on the Slavich plates.
So, I'm thinking... longer exposure and different plates? I've used up the twelve 2.5 x 2.5s that I got with the kit, and don't really want to break in the box of 6 x 4s that I got just for test purposes. Are there any better plates that work with JD-4? Or do I have to go for scary chemicals?
I'm thinking of a more powerful laser too - if anyone can recommend a diode with good stability and decent coherence, I'll be interested to hear about it.
In terms of vibration: My setup is a heavy (full) dresser as a base with the object and plate mounted on a mousemat, which in turn is mounted on a large plate filled with salt. The laser is pegged into a glass full of salt, on top of a brick, on top of a mousemat. I think it's fairly stable...

Slow down. You seem to be trying too many variations too quickly.
Go back to the simple plate on top of shiny coins for your first hologram--the simplest of all reflection holograms. No transmission holograms. No multi-beam. Don't even try something where the plate doesn't touch the object. If you cannot get that to work, then you have some fundamental issue with technique.
