Thanks Jim. Looks pretty neat :)

To those who have completed their systems: what type/power macro lenses do you use? I know some have used the macro portion of their WA adapters, but some must be using regular macro/close-up filters. What power are you using? Can you zoom through these a bit and still pull focus on the projected image? Since this is the only portion of the project that involves purchasing a legitimate piece of equipment I'd like to be well informed about what works. I'd like this thing to be as compact as possible. Thanks!

this is just a thought but would the material they use for rear projection TV's work for the static solution? same principle something is projected onto it from the rear and you see it on the other side. might not pass enought light thru though for this application.

Now if anyone has acess to some of this material it might be worth a try

gg from zenith 50`s
 
hello people.!

Vendi, you are wrong about NO GROUND GLASS that provides a good static solution.

I went to a used photo cam store and i found a cam by ZENITH that has a GROUND GLASS with a DIFUSING (fresnel?, im a brazilian, here we call it `lente difusora`)

lens attached behind it!

man, IT REALLY WORKS >expletive removed< GREAT

the GG was made 40 years ago. is perfect, besides only a scratch that i dont notice everytime.

and the grain is very little, it only adds a more film look aspect.

no vignette, no nothing, cause the DIFUSING LENS behind it just EXPAND the lens image to the WHOLE GROUND GLASS!!

if you tell me where to send the video i made (without the things adapted to a box), i will upload right now.

Hey Daniel,
If you want to send the video to me I can post on my site.
Can you also take photos of your rig and post them.

Just an idea.

ZENITH GROUND GLASS
 
...AH, the man who selled me, said that its almost impossible to find one of those these days!!!!
i bought it for 10$ .

NONE of others photo cams ground glasses is the same CLEAN as this one.

Jon Kamps December 22nd, 2003 05:55 PM

scratch my rear projection Idea all they use is a fresnal no acutal screen. looking back on what daniel discoverd though maybe we should take a ground glass and a fresnal sandwitched together?

"the grain is very little, it only adds a more film look aspect."

I said that no GG will work for high quality. You saw the grain, and I know exactly what you saw.

To me it only produces ok results. Try move the camera and have objects move in front of it, also try different light angles. The grain is certainly not film like, the grains are static, makes it look like it's shooting behind a glass (which is true).

If you scale your video to smaller size, this works fine, because the grain will be averaged out and not as visible. But for real things like DVD, or indy film, higher quality is needed. But again, Super fine GG will produce ok results, just not great. If you think it's good enough, then it's good enough.

If you want to produce an upright image, take a look at my design, better yet, improve it.

pff
 
I said that its very little.

i know that im talking about.

i cant see no grain even when the lens projected image is not covered from light, i dont see any grain at all!!!!!!!!!!!!!!!!!!!!!

i put this on the tv, and no grain, and the test was even without a cover.

i can show you the footage.

by the way, have you ever tried to use a real photocam ground glass?

man, ZENITH is RUSSIAN COMPANY, they know it all.

daniel,

i didn't tried it yet, but here in poland you can find TONS of that ZENIT (wthout "H") - if this is the same producer - this was USSR 35mm still camera. Are we are talking about the same thing? What camera (type/model) you have?

if you find it interesting - (the zenit ground glass) - i can check here and there and maybe send it where needed. i'm sure that you can find here zenit in proper working condition - the whole photo camera (WITH the lens) for 15-20$ max (which means that theoretically GG will cost much, much less).

so, if yo buy the whole camera - you can use the GG and experiment with the rest - the lens, maybe also pentaprism - who knows. but i'm not sure about packing and transport fees...
anyhow - at least you can try.
is it possible to find somewhere your tests with that ZENIT GG?

a ball inside
 
it not a new zenith camera.

it was from an old zenith, 50's

the seller told me that those flat ground glass (with no grain) is almost impossible to find these days cause all the cameras are with the same glasses but the flat ground glass is marked with something, like a ball inside it.

ciao

Don Berube December 22nd, 2003 07:15 PM

Hi Daniel,

How is it spelled on your camera?

Is it spelled like "Z-E-N-I-T-H"? (with an "H" at the end?)

OR is it spelled like "Z-E-N-I-T"? (with NO "H" at the end?)
