Red and orenge filters

[marciofs]

My enlarger came with a red nd an orenge filter.

I have being using colour filters on my lens to shoot with black and with film. But I don't know yet the effect of theses felterd on the enlarge lens to print black and white. What they realy do?

They, depending on the paper you are using, allow you to center or compose the image on the photopaper without exposing the paper -- basically safelights for your enlarger.

Most photo paper is not sensitive to amber/orange light. Some other material such as litho film and some photo paper is not sensitive to red light.

Speaking of the under lens filter...
Does anyone know of a source of the red plastic filter material?
The filter for my enlarger is missing the red filter element and I would like to replace it, if possible.
All I need is a piece probably less than 3 inches square.

Depends on your enlarger type.

See here for a few possibilites.

It is for a Durst L1000.

The Kodak color printing filter looks like it might work, but I don't need a piece that big.
I'm also being cheap on this repair since it is not a "have to fix" problem.

Would a Cokin or Lee red filtr do the job ?
Failing that, contact Edmund Optics and see if they have a standard product line to offer.

In all my years of printing, I've never used the red filters attached to many enlargers. I never quite saw the point.

It might, as long as I could grind it to drop into the round holder.

I don't use the red filter much on my other enlarger. But once in a while I have, so I figure why not get it repaired.
But because it is not something that I use often, it is low priority = cheap fix.

They might come in handy for exposing more than one neg onto a piece of paper and one only has one enlarger. Or perhaps rechecking focus during exposure/burning. But they are a low-priority item for most people.
