Yes, please.

Like many things, this becomes obvious only after it gets mentioned. Thanks for the tip!!

A hint when dealing with Anchor Optics:

Always buy at two. You get a 30% or so discount, so the second is at better than half off. Plus you will find out later your really needed two, anyway.

I'm building my first setup using "Homemade Holograms" by John Iovine and wanted to ask everyone here if anyone has any of the following available before I speculate exactly what I need at Anchor Optics, who are not too helpful. Don't pass over Anchor Optics too quickly. The experimenter ...

It's just a projection on a large glass screen, no?

I retried shooting the push pins, but used the bleach from the JD-4 chemistry in place of the JD-2 bleach. The result was a little bit of blue fogging on the plate, and still something of a mottled, scummy view through the plate, but the image itself is much brighter than the JD-2 bleach version. It...

The attached photos are of a hologram i made of color push pins in a plastic cup. As with most attempts at photographing holograms, the actual is much better than the pictures. Still, though, I think you can see that it is looking through a scummed up window at the pins.

Whenever I have had problems I would describe as mottled I look at processing. Is my squeegee good, am I stirring my chemistry... I fall into the "doesn't squeegee at all" camp. I tried it a couple of times with PFG-03. I didn't realize how soft the gelatin was. What a disaster. My unders...

I'm having a problem. My post recent attempts to produce simple Denisyuk reflection holograms have yielded very poor results. It is as if you are looking through a scummy window when viewing the image. The image is well-formed, but partially obscured by a mottled cloud. My setup is stable according ...

This is a good group of people here. Let me add my "Me, too!" to those extending special thanks to Colin for his past dedication and to Ahmet for taking up the baton so quickly.
