Per-Anders,
This reminds me of a situation some years ago.
There were adds all over the photo magazines announcing a revolutionary achievement:
A film cartridge the you inserted on any 35mm camera and transformed it in a digital camera.
There was pictures of the product in the adds.
It fitted perfectly in any camera's film compartment, included a CCD and had batteries inside.
There was plenty of enthusiasm, the professionals were waiting for that product to be released.

It never did.:bawling:
It was discovered that there was no final product, they couldn't make it practical, and the pic in the adds was fake.:clown:

Do you know if there was ever a serious working prototype
and they just couldn't make it into a product? I also remember
reading about it . I also remember reading about a "digital
back" for SLRs, so you could take off the ordinary lid to the
film compartment and replace it with one including a CCD,
but that never seems to have become a product either. I
have even asked about it in shops, but nobody has ever
heard about it, so it was probably just a product idea that
they never produced.

Pre-amplifying directly as close as possible to the cartridge may be a good idea.
That's used on some studio microphones.
But passing the signal through and ADC?:eek:
And then a Dac in the end?:eek:
S' stupid idea!:bawling:
:clown: :D

In the 70s Yamaha had two preamps with an fet attached to the cartrige at the head. Powered from the preamp, this works very well. I think it was called H1 and H2.

I think the real problem is probably that camera CCDs are generally a whole heck of a lot smaller than 35mm film.

You're right. I didn't think of that. Probably they had hopes of
making large-size CCDs, which would have given very good
resolution indeed. I suppose the yield turned out too low to
make it feasible. 35x24mm without a single defect is quite
a requirement.

Yeah, but back 15 yrs. ago they weren't. Some digital adapters did make it to market. Mamiya had one for their RB67 medium format camera.

Ah, so that is probably what I had heard of and then assumed
Nikon would eventually make one for 35mm cameras, which
they never did. :(

Now when you say it was Mamiya, that sounds familiar. It
was probably their adapter I read about.

Yes, they made prototypes.
Make no mistake, that thing fitted directly on the film compartment of any 35mm camera, it's not a replacement back.
It had the format of a 110 mm film cartridge, the CCD being in the midle.
The problem they found was that inside that thing the space was so limited that the best battery they could fit there last only some 5 minutes.:clown:
 
Thanks Carlos.
Yes I realize what you talked about and I remember reading
about them too, whenever it was. I think the back adapters, that
we now know existed at least for some cameras, came first.
I remember reading about them much earlier and then, later,
about this "film replacement". I'm not surprised about the
battery problem. That was the first thing I wondered about
when once reading about them. Seems I guessed right at
that time. It wouldn't work. :)

Why would you pass it trough a dac anyway, this is 2004?

That digital film cassete: http://www.siliconfilm.com/default.htm But the site seems suspiciously empty.

As for the CCD's being smaller than 24x36, that is a problem all digital cameras fight with and the reason you need "digital" lenses (with a far wider view angle). But there are 24x36 CCD's! Cameras like the Canon EOS-1Ds use this 11 megapixel beasts.

Yes, I remember now reading that some cameras have large
CCDs. Come to think of, all the SLRs that take normal lenses
must have such CCDs. That probably explains why they are
so expensive, assuming the yield is low for large CCDs. That
might also explain why Hasselblad's digital camera costs
$50000 (apart from the name, that is). It must have a 60x60mm CCD!!!

Don't believe the digital amp thing (yet). :angel:
Convert vinyl to digital while listening?
Stupid thing.
For recording your vinyl, maby. :bulb:

Yes, that's it!:cool:
Can you imagine how the image passes from the CCD to the LCD screen?:clown:
Make a hole on your camera to pass the wires?:xeye:
This is all Photoshop to me.:whazzat:
