If one need just a couple of "scans" for internet or other less demanding purposes. The quality might be enhanced with getting a better lamp or just aligning the camera better. The sample photo wasn't 100% focused either ..

But what is significant here is the evidence for Inca culture in Finland.

I've shot slides off a light table hand held, they came out OK. I was thinking of some sort of structure to hold the camera steady and parallel... but eh...

Nice shot, is that an enlarger you're using?

Opemus IIa. First I thought that I'll take some parts off it to make a small light table, then I thought - there is a film holder and lamp there already and just turned the thing sideways.

Here is some of the artist's work:

Here are some facts about the place, if you plan a trip to SW Finland next summer: http://tinyurl.com/ybsufo7

Seems to me that this is a cheap alternative only if one already has an enlarger laying about.

I've found a cheap, and very good, alternative to scanning 35mm slides and negatives is to use a slide duplicator. I modified mine so I can even dupe negatives with it. Because my DSLR is a 1.6x crop body, I bought a "digital" slide duplicator, which screws into the front of the lens. I paid about $50 for this duplicator new, but sometimes they can be found for less than this used on eBay.

IMHO this is a far better and elegant alternative if you have got a Fullframe - cam... like my EOS 5D or a Nikon FF



So i realized my kind of "high-speed-scanner". Its a NOVOFLEX M39 to M42 Bellows with a NOFLEXAR 4/60mm and a slide duplication unit.
You can insert slides in all kinds, as negativ films also.

The shown unit makes 1:1 copys from each 24x36 material.
A flash (not shown) brings enough light for each kind of film or slide and is correct in Kelvin Temperature..

So here is my first result.. from 1975 with a cheap ektachrome slide..



Instead of this, you can also buy a cheap Slide duplicator on ebay for about 25 Euros. But mostly you cant do 1:1 copys with a crop cam.

I have almost similar setup for a crop camera. With my bellows (Pentax Bellows A and slide copier) it just needs exactly 75mm focal length to get the whole frame. I'm using Pentax M 75-150/4 zoom (since I cant afford the limited 77/1.8 Smile).

Here's some samples:

I have the same as Soikka. I used what was handy - the 55/1.8 was closest and just stretched enough to get the slide...

Actually you can. That was exactly why I was referring to a lens-mounted slide copier in my above message.

For my 1.6x crop body camera, a zoom lens works best for a 1:1 dupe because it requires a focal length of just a bit under 70mm.

If I had a FF camera (someday!) I would also be using a bellows with slide duplicator setup. It offers the best results with the least amount of compromise. Except for using a Bowens Illumintran or equivalent.

Sorry, didnt read your post during writing and editing my own Shocked Very Happy

But it seemed we both do agree the same idea.

Do your setups handle 120? This was the whole idea .. should we star talking about MaF as Manual Focus and MeF as Medium Format. Smile

If your enlarger can handle 120, thats a great idea. But i would do some corrections on that. Instead of a lamp try to use a mate plate and a flashlight inside of the housing, no condensor. In aditton to that it would be a nice idea to use a compendium für the lens the reduce unwanted lights..

Thanks for the tip. Light colour is the biggest problem, my tests had strong yellow-red tint that couldn't be removed.

You might try setting the camera's white balance first... with a clear bit of film, or something translucent, I'm not sure what would work best
