Jonathan:

Welcome to APUG.

I'd suggest looking through the "Getting Started" section which is in the "Applications" section of the Ilford/Harmann website.

Here is a link:

http://www.ilfordphoto.com/applications/page.asp?n=9

In that section, under the link "Processing a Black and White Film" you will find a link to a pdf document with the same title. There are specific recommendations there for appropriate chemistry, plus information about capacity.

There are a lot of other good suggestions (I myself am quite partial to many of the Kodak alternatives) but the Ilford information is excellent for beginners, especially those who are in the UK.

Hope this helps - and have fun!

Matt
