They're all Denisyuks; the last two are made with 514nm argon light on VRP-M. The exposure on those was a bit low (8s) when it probably would have been better around 15-20s. (The argon is set to <5mW so that I don't have to wear safety glasses when working around the table)

Very nice. What is the very bright yellow spot in the holograms?

It comes from the fact that the object (a swiss army knife) is reflective...
