    Wolfgang -- Thanks for the tulip and the explanation -- it's really helpful and I now know where I went wrong. I guess I'm so focused on my blacks and highlights that I usually let the mid-tones fall where they lay. Normally that works fine but in this case I got an interesting result. I'm still using your easylith developer because I'm very much a beginner at this, but with every attempt in the darkroom I'm learning more and more.

    For some reason I can't attach the photos to this message (just like I can't use the smileys or any other features) so I'll post them in the technical gallery so you can all see what I'm talking about.

    New 'PF' type problem?

    Hi Rachelle
    Actually I don't think this this really is pepper fogging. I think it is the grainy look you get when infectious development moves up from the blacks into the mid tones. It can look very good too - just different, as with your Buddha print. there is no right or wrong with lith. It's interpretative and if it's what you like - it's right ;-) But as Wolfgang points out, there are various ways of changing it.

    Those who were around doing lith in the days of the 2nd generation Sterling Lith paper will remember the PF effect. On the 1st print it appeared on (usually about print 3) it looked like pepper sprinkled very lightly over the print. Notably it was as obvious in the highlights as the midtones, in fact more conspicuous there as it was so out of place. The next print would be more affected and the following one severely so all over. The cure was simple (once the cause of the problem was diagnosed!).

    A few other papers have shown it to much smaller degrees (e.g. MACO) but it isn't much of a problem now.
    But some papers have other random infectious development problems occasionally. Forte's 'black spot syndrome' is an example.

    Interestingly I have just come across a few one (for me) today.
    I have been lithing a new Kentona batch (an emulsion I have been using for years in various incarnations) and it suddenly develops little black spider shapes all over just when the main blacks emerge. This is a new one for me and so far I have found that it didn't respond to various amounts of sulphite addition but did to a stronger developer. I'll have to explore this more over the next days.

    Has anyone else had this?

    Thanks Tim for clearing that up.

    As noted in my previous posts, I wasn't really sure what it was since I'm pretty new to lith printing, and could only think of pepper fogging, which I've only seen in your books (although the pictures are kind of small to see the 'pepper' effect clearly). It just seems like such a strange effect -- I like it, but it would just be a matter of figuring out how to achieve it purposefully (instead of randomly) for particular images.

    I've been using Kentona as well but haven't noticed the little spider shapes (yet!) that you've mentioned.

    Actually they are quite big spiders! up to 1/2 cm across.
    No, I've never seen them before either, but that is how PF started on the old Sterling paper. One day it was just there. i'll talk to kentmere and Ilford tomorrow, and do a few more tests.
