Tray Developing 5x4

Looks as though its dropped off the DNS list to me Barry
Hi Ian,

We have had some issues over the years as the domain was originally set up by another. We often do not get renewal notices and I suspect this is what happened here. We are just awaiting a response from our isp. Sorry for any inconvenience .
 
Ian, here's another option. I heard about this technique used by a professional for developing single 8x10 sheet in a tray, but it should also work with 4x5. He uses a Hake brush (normally used for watercolor) with very soft bristles, and agitates by lightly stroking the developer over the film with emulsion UP; the brush's soft hairs do not scratch the film even if contacting it (don't know if he ever used Foma, though!). Agitation is done by stroking slowly in letter "W" fashion, once lengthwise then once crosswise, then repeat. When done he just rinses the brush under running tap water, then lays it across the top of a glass jar to dry, avoiding contamination. I've not used this method yet for single 8x10 but have just bought the brushes from this US source:

You may have a source in UK. A set of several width brushes gives room to grow into formats larger than 4x5.

Much the same thing from Silverprint.

It sounds like a technique from the days of glass plates. They seemed to use one tray and pour the chemicals in and out instead of transferring the negative from one to another. Handling wet glass plates in that way must have been hazardous for both plate and operator. With a blue-sensitive emulsion, it would have allowed local control of density and contrast, by inspection.
