Filipe, good job.

Do you have access to a DCG hologram that is made by one of the gurus like Dave, Joe or someone else? I think it is hard for you to tell (and me too) how close you are. I think seeing a very bright hologram that is clean is useful.

Dave are you ever going to e-bay another DCG? I bid for the last one you did and loss because I was in Japan. Wouldn't mind another crack at it!

Very nice hologram, congratulations! Is a direct Denisyuk image right?

Congratulações ao colega Português! Creio que es um dos únicos em Portugal com esta qualidade em DCG...
Existem alguns termoplásticos que funcionam como colas a quente os quais definitivamente barram o vapor d'agua muito mais que o epoxy, que poderia ser usado para selar entre vidros.

Hello all!

Hey Joe!
I just bought some nice UV adhesive, I'll try it on the next holograms. Thanks!

Yo Tony, I really don't know how close I am, I still have plenty of dust, sometimes
fingerprints on the emulsion! =) It is really hard for me to keep the process clean...
The one thing that I think it is most important is consistency on the results,
most of my tries fail miserably, so I can say I have some lucky holograms! =P
What is the success rate you would consider good?

Olá Sergio!

Yes it is a direct Denisyuk, placed over a typewriter's keyboard, no glue, just luck! =D
É bom saber que pelo menos há alguém que fala português por este meio da holografia,
não sei mesmo se em Portugal há mais alguém que faça DCG? Já procurei por holografia em Portugal
e só encontrei uns exemplos numa universidade qualquer...

Thank you all for your encouraging comments.

Best regards
Filipe

Hey Filipe,
If you ever can get a hold of a really good DCG hologram it would really help you a lot in seeing just how bright they can be. I was hoping Dave was going to sell some more of his on e-bay, I wouldn't mind getting a Dave-o-gram myself.
As far as success. When I was a new-be like yourself it was always hit or miss. Some nights, nothing, then I would go crying to the forum guys John, Joe, Dave or Danny and get a few pointers. In time I was able to make a DCG hologram most any time. But....... there is a difference now in making a hologram, meaning there is an imagine on the plate and making a great hologram. The difference between an extremely bright hologram and an average one is very distinguishable. As John use to say (gee I'm talking like he's dead or something) the good ones pop even in very low light. Once you make a couple of these, you'll be hooked. You cannot take your eyes off them. But that being said, the effort of making one of these (at least for me) is very difficult. For me the problem is time. If I can't dial in the hologram in 3 or 4 plates then I'm screwed. I only have a few hours here and there to shoot. The key is to be able to take a shot, look at it and asset how to change to next one. If your not sure, change something that you are sure will move the film outcome the way you'd expect. So if the image is white, you know more fixer time. But playing with the parameters you'll develop that feel.
Lastly take good notes. Almost each shot I take I make a photo with the parameters I shot it in and put it in power point. I then can see how each nights shot went. Set up a fixed light and a way to shoot the hologram about the same way each time and keep at it. It will yield benefits later on.

Keep up the good work,
Tony
