My enlarger doesn't have a timer, how do I expose my prints?

Question

So I'm slowly getting into developing film and bought me a darkroom equipment. I got me DeJur Versatile Professional enlarger that works fine. It didn't come with a timer and for what I've seen you need a timer connected to the enlarger (not very sure about this) in order to set the exposure time (?). And I have no idea how would I be able to set the exposure time. Since the enlarger is so old, I haven't been able to find the manuals. I needs someone to help me. Thanks so much

Answer 1

A timer hooked-up to the enlarger is a basic necessity. However, you can go to the hardware store and construct a hand-held off/on switch. You will also need a clock with sweep second hand that is illuminated. If too bright, cover with red or yellow transparent holiday rapping stuff.



To proceed:

Insert the negative and compose and focus. Compose for an 8 x 10 inch print.

Set the lens aperture in the middle of its range, likely f/11.

Under safelight conditions, place a test strip of paper so it falls in about the middle of the projected image.

Test expose a strip at 4 seconds, another at 6 seconds, another at 8 seconds etc.

Develop the test strips by time, not visual. Time in the developer will be 90 seconds.

If all too light, double the suggested starting times. If all too dark cut the times in half.

You truly need an enlarger timer to proceed in comfort. Why not ask Santa deliver one and put it in you stocking.



Best of luck

Answer 2

I used a manual switch inline with the enlarger power cord and a watch for many years. You can get the switch at any hardware store.



Better yet, find an old GraLab timer on eBay.

Answer 3

You have a watch with a seconds hand? You have the on/off switch?

Use your watch to time the exposure and flick the switch when the time is up.

There will be enough stray light from the enlarger to let you see the time.

I did it like that for years.
