Default Paper Negatives

I am currently trying out exposing onto paper with a 10x8 and would appreciate any tips from those with experience on this, especially with regard to choice of developer and control of contrast. The paper I am using is Ilford RC multigrade.

Hi Pete,

Controlling contrast is the key. If you do a straight exposure of a piece of paper then contrast will probably be through the roof. There are some thing you can do to tame it:

A. Develop the paper in a weak print developer or use film developer.
B. Use a yellow filter which tends to overcome the paper's sensitivity to blue light.
C. Pre-expose the paper to a weak light.
D. Overexpose the paper and give it a briefer time in the developer.

Here's a couple of posts on my blog that might be helpful:

And one from Andrew Sanderson, one of the foremost exponents on paper negs:

Thanks very much Brock. My own thoughts were moving along similar lines. Have been trying a 00 grade filter in front of the lens which seems to help.

In front of the camera or enlarger lens when contact printing the negative?

A yellow filter in front of the camera 'lens' including pinhole, is also very helpful to the negative in giving a wider range of tones and lowering the contrast slightly. An extra stop of exposure is required.

I have also tried diluting the paper developer for the neg but found this to be of no use, although the author of the book I read it in did, so worth trying for yourself.
