I have tried to paste a picture of this set up without success also tried the img box ,can someone please explain the picture upload sequence to a thickie! Many Thanks jeff

First, you must upload the pictures somewhere online.
If you have your own webspace you can do it there.

If not, you can upload the picture here:

With the 'admin' box you can upload pictures.
Then, click on the picture and copy the URL.
Then, paste the URL in your post.

Like this:

Thanks Roger!

I've taken apart one of those Optex transfer boxes to see how I could use the mirror. You were right all along. I place it at a 45 degree angle from the enlarging lens, which was seated in the projector's socket. At this point the image was properly orientated and about 1 cm diagonally, so I then lined up the camera and 24x macro lens with the image in the mirror and filled the CCD's sensor. Even though everything focused properly the image had a ghosting effect and didn't look too clear, and there also seemed to be some chromatic distortion.

Thanks for the tip, I'll look around and obtain a first surface mirror instead. What about the mirrors in those VHS camera viewfinders? I have about 3 extra VHS cameras that are broken in one way or another, but the viewfinders are still functional.

I guess there's no way to get around recording 8mm film in real time and having the image properly orientated without the use of a mirror, having the camera aimed at the base, a condenser lens, prism, or having to mount the camera upside down. This is my only issue with regard to realtime recording. But I can settle for a projector with the enlarger in the socket, a first surface mirror angled at 45 degrees, and a macro lens pointed at the resulting image. In either case this is much better than anything I've ever achieved simply recording off of a screen.

I hope to build two different rigs, one for realtime and another for my computer, which would only require a macro pointed at the gate since I can then rotate the image once it's on the harddrive.

Concerning the use of an enlarged projector gate, I spoke to a friend who used to operate many Telecine houses professionally. He told me using an enlarged gate, it would only serve to expose more of the dirt around the borders of the camera lens, and would throw off the aperture. I have a few files at home that I can use to expand the gate, but I'm still debating it. In any case I can just crop the film once it's in on the hard drive, and do so without having to enlarge the pixels.

OHP projectors and microfiche readers use surface coated mirrors. I found a few discarded in a library dumpster. I think the camcorder viewfinder mirrors may be a bit tiny. Don't use chemicals cleaners or wipe and polish these mirrors, the silvery surface coatings just melts away!

Hello VideoFred

Just wanted to share a great idea that I found out and tried last night. Don't know if this have been tested before, but my results were great.

Take the following lamp:
http://www.ikea.com/webapp/wcs/stores/s ... r=00065671

Grab all glassfibres together and mount them as a squere, larger than the film frame. Mount a matted white plastic piece in front of it. All small light sources will eliminate the "hotspot" in the middle, as you will have hundreds of "hotspots" over the whole picture. This works exellent. You should try this. The LED in this unit can easily be changed.

Good luck with your new unit.

Hi Rolle,

Welcome here!
It looks like this thread brings new members to this forum 8)

The fiber light is a very good idea. The Thomson Shadow is using fiber light, too.

But my results with the Luxeon Leds and the reflector are so good, I think I'm gonna keep this setup.

The unit is almost ready, now. As soon as I can find some time, I post some pics from the new Led light source, the electronics and some new frames.

Fred.

Hello Fred,
I've been reading some of your topics over the past couple of days and trying to read your website. The online website translators -- while amusing -- aren't that great.

Anyway, I'm interested in the camera side of your project. I have a workprinter with a condensor lens and would like to try and do something like you've done. I can't work out whether "the blue box" is a still camera or a video camera. What is the original purpose of these cameras?

Also the lens. You said it was a sony 45mm lens. Do you have the model of the lens so I can search for it? I assume that is an extension tube on there. I don't know much about these things like others on this forum, I'm sorry about that.

Thanks a lot for any help.

Hello again Fred.
Must ask you, your cam is it analog output? If so how on earth do you get so good A/D-convertion. I have tried several A/D-boxes and so on with not so good result. So I threw thew away and bought a similar cam like yours but with FireWire:

"the blue box" is a still camera or a video camera. What is the original purpose of these cameras?¨

It is a machine vision camera. A video camera. It is using fire wire, but with a different protocol then DV cams. Also, maximum frame rate is limited to 15fps, and it captures progressive, not interlaced.

Also the lens. You said it was a sony 45mm lens. Do you have the model of the lens so I can search for it? I assume that is an extension tube on there. I don't know much about these things like others on this forum, I'm sorry about that.

Well, two years ago I did not know anything myself.
So I asked like you do :lol:

Now, about this lens: the extention tube is part of this lens. The actual lens is very small. If you Google on 'Sony 45mm macro lens' you will find more about it.

My cam is full digital and fire wire only.
Very similar like the one you bought.
I would like to see some results from your cam!

I know some people do not like the pictures from these machine cams.
But, with help from Thomas, I did comparison tests: workprinter 3CCD vs my cam.

Of cource the 3CCD gives better colors, but my result was not bad at all.
And with my new led light source color reproduction is improved.

And my system is very easy to use. And you barely see the difference on TV....
Watching my 8mm films on TV with a decent quality is my end target, nothing more.

Thanks a lot Fred.

If you Google on 'Sony 45mm macro lens' you will find more about it

There was suprisingly little, at least on google.co.uk. Most of the finds were you talking about it in various forums, which was quite funny.

I see Paul Cotto's using one as well.

Looking through the archives I see that the gaf projector used for the workprinter is unable to take a lens up close because of the width of the lens. That's probably put a damper on it for me. Having said that, the sony looks quite narrow, at least in the pictures. I think it's going to be a tough job getting one though.

Thanks again Fred.

Hello Fred.
When you have time, try a C -> Nikon adapter and a Nikon macro lens for 35mm camera. This makes wonders, I'll promise that.
Hope you put up some samples soon.
Could you take some pictures of your LED-setup please. I'm curious.
Have a nice evening!

I don't want to go too far off topic, but I was curious to see if anyone knew of any adapters that would let me use a CS Mount on a 37mm thread?

Thanks!
