Value of money and cost of technology

I did too, ours was Pan F IIRC .

yes sounds familar, my memory was more of trying to expose the film to ligh t without damaging the soft emulsion, getting it almost of the spool then g etting it back on again. I still dont understadn why we were doing it, per haps it was the in thing at the time.

I was told to use pan F for the fine grain, still wasn't sure why.

My favourite film of that time was HP3 I bought it in 50ft spools.

For me it was free, just get the chemicals from the lab. But I'm not sure whether pre-paid B&W reversal agfa film was cheaper than colour slide film of the time. Not many people seemed intersted in B&W sli des even though plenty did B&W prints and more people in my camera club did colour prints than B&W slides.

there was really no upside to B&W slides. With colour there was.

Yeah the fact that it was colour so what was the point of B&W slides, and w hy get me to process them ?

I assume because it was cheaper than using colour slides but B&W reversal f ilm which was more expensive than colour neg and no cheaper than colour sli de film at the time, so unless there was some 'art' reason that escape me a t the time.

whoosh

As I said before, cost. My school couldn't have afforded the number of slides we produced if they had been colour, and they were more than adequate for purpose.

Sure. What I meant was B&W slides have no upside over prints, unless you specifically need slides. Colour slides had better colour than prints.

There's quite a lot of 120 film to be had on eBay and there are some relative bargains in fresh film if you look for them. Expired film can sell at a premium to the "Lomo" crowd but there can be bargains there as well. I've just loaded into a film back some HP4 which expired in February 1980 for which I paid a little over £1 a roll. To compensate for the age I derated previous rolls from the stated 400 to 100ASA and I've been pleased with the results.

Another trick is to use 35mm film in a medium format camera. Some cameras, like my Yashica 635, are designed to be dual format. Otherwise, use 35mm/120 adaptors and run the film direct from the cassette or use bulk 35mm and load it behind old 120 backing paper. The film will be exposed through the sprockets as well which can be a pleasantly retro effect and gives a full 35mm x 44mm in my Bronica (other formats will give approx. 60, 70, or 90 for the other dimension) If you don't want the sprocket effect, the cropped frame will still have a larger surface area than bog-standard 35mm.

OIC. In this case, slides were needed as they were to be used in lessons, and projected.

I still have some Photoflood bulbs - I recall making a series / parallel circuit for them.

Slow is good for my more elderly vintage cameras.

I've been meaning to try that in my Yashica 44 but not enough round tuits ...

Yes they do because like colour slides they can be projected onto a screen something B&W prints can't have done to them.

But were difficult to do at home or even in a school science or art lesson.

Niether the art department or the physics lab were set up to do colour processing whether in prints or slides, but the art dept had a darkroom where they taught basic processing of B&W.

Just heard the words

"Make sure your robot can pick up a duck."

said to the class from the lecturer to the group of teachers in my lab today.

Not the sort of thing I hear in this lab, other labs might be differant.

and their users ;-)

I've got a polaroid land 110B with box somewhere.

Think "Epidiascope"! that's how we often saw images at school.

Exactly I win the point, as that is exactly what they did. That is the upside.

A feature of geography classrooms.

Actually, an 'epi' will do. The 'dia' is the slide projector bit.

ok. Let us know if you can manage basic reality.

Yes I do and can, but not perhaps yuor version of reality. How to develop film, how to print prints and how to 'make' slides.

How are slides aka transparancies differnt from prints and negatives.

It's called education.
