Back from Spain

Well, we’re back.

It was a fun, new, exciting, thrilling, tiring, frustrating, adventurous two weeks and we’re back home safe and sound.

Some quick highlights are:

New toy

Along with dealing with the silliness on The holography forum, I’ve been playing with a new toy in The form of a tablet pc the Averatec C3500 . In fact, I’ve written all this on the tablet screen.

I still need a lot of practice though.

This took way too long to enter.

Gallery updated & new MSDS added

I’ve updated the gallery page with a simple (Paypal) way to purchase almost all of the holograms featured here and I’ve also added a few new MSDS documents to the site.

Index matching, cont

After these attempts I’ve continued refining my index matching methods and I’m two for two. I made a hologram this morning with the second piece of film that I’d TEA treated yesterday and the final hologram is nice bright and clear.

On the other hand, I’ve got to improve my pre-index methods as there were several small pieces of lint and one thread that was apparently on the film before I put it on the glass.

Fortunately none of these show up in the final image.

Index matching

Anyone have any foolproof methods for index matching sheets of PFG-01 roll film to glass? For 4×5" sheets I’d used both mineral oil and lamp oil with decent success, although I detest the messiness of it.

Minas Tirith

I’ve been working on a commission from a co-worker for a bit now and the last few days have been spent doing tests (I generally manage to get one in a day during the week) of new bleaches and color swelling.

Weekend fun

This weekend was a good one for holography (as well as enjoying the weather with wifey).

On Saturday I made a large copy of the Jesus-gram (which I gave to Andres) and I later got a wild hair and decided to take the time to re-do my canopy. I haven’t been happy with it because I originally made it shorter than it needed to be and there was one corner that was hard to get past.

Jesus!


Last week Andres came over to make use of my master layout (he had his table set up for copies and really didn’t want to tear it down) to make a Jesus-gram.

1/2 wave plate holder

There are times when you need an inexpensive way to rotate an optic and not too long ago I had just such a need.

I purchased a few half-wave plates off eBay some time ago and needed a way to rotate them without breaking the bank.

It was time to go to the hardware store and see what I could find.

Want a photopolymer that works?

Over the weekend I had the time to start testing the latest batch of photopolymer from Polygrama and I have to tell you that it was a pleasure to work with. But let me back up a bit and take you to the beginning of the testing session.
