(PC) Projector as enlarger for B/W prints

[photo-vinc]

Hello,

Does anybody of you have an idea (or even experience) if it is possible to use a computer projector as an enlarger for B/W prints in Darkroom.

The resolution is way, way, way, way, way too low.

The colour accuracy is way, way way, way, way, too bad.

This is a bad, bad, bad, bad idea.

Colour accuracy would be less a problem when making B&W prints I think. However the resolution is a "show stopper" (I could have calculated this by myself before asking here)

I tried it a long time ago when looking for some soft effects in BW.  It worked for that, but further experiments "defocusing" my enlarger yielded better results and more control.  So even when I was looking for fuzzygraphs, the enlarger worked better!

Well this  one gives you at least 3 Megapixels. Should be ok for an A4-sized print...

Unfortunately it is very very very expensive and very very very bright. Yours for 384,756 AUD...

Why not make a digital negative from your printer and contact print it?  You can do this by printing on acetate and placing glass over the negative.

I once tried using a slide projector as an enlarger when I was a boy and couldn't afford the real thing. It was far too bright and had a long focal so I had to tape the paper to the wall acros the room for a 1 second exposure! even so the prints were all muddy.

with hindsight i should have made a black paper aperture for the front of the lens and tried to find a non-inflammable way to minimse light spill. Still the brightness saved on developer:)

the memory amuses me to this day.

It should be possible to "find" an old enlarger really cheap as everybody is switching, people are throwing them out (sadly) try your local photographic club or even your local photographic store, they may have some left they can't sell?  woth a try.  Wayne

The theory works

My first enarger - a slide projector - I used a bottle top with a hole drilled in the middle  as an aperture

My second a real enlarger I used a nikkor 24 to create large prints

All in mums bathroom of course - the carpet stills shows the damage 20 years later

My first enlarger was a slide projector as well.  My brother and I made numerous modifications and were quite pleased with the results as we had no money to speak of.  After that it was Omega enlargers and finally Beselers until I went digital.  

While I have fond memories of that slide projector and what we were able to accomplish I'm sure glad I no longer have to work in my parents' basement.
