Very impressive image. Good "evenness" of the image compared to some other efforts I've seen.

I have not tried making any emulsion (yet), but I've had some ideas bouncing around in my head, that I thought I'd bounce off you to see what you thought of them.

Two main themes at the moment. First is a (maybe) novel method for forming emulsion, which would allow daylight coating (if it works). Basically, I would mix colloidal silver into gelatine, and then coat the support (glass or flexible) with the gelatine/colloidal silver emulsion. (At this point, the emulsion would be black, entirely DMax across the surface.)

Then, I'd go "lights out" (or, put it in a tank), and soak it in a halogenating bleach (i.e., potassium bromide and potassium ferricyanide, to make a silver bromide emulsion), and then, rinse, and dry.

In theory (my theory, at least), I'd then have a silver bromide emulsion (non-color sensitized).

You think this'd work?

Next theme is coating methods. From what I've read, the "blade" technique causes people a lot of grief, trying to get a nice, even coating. It seems to me that this technique will work nicely if everything is done just right, but, it is inherently lacking in any "self-regulating" characteristics,

So, what I am thinking is that two "possibles" would be to either spray the emulsion onto the support, or, use some type of laminar flow system to "run" it over the support.

A third possibility, which I think I recall having read that G. Eastman patented as his first "simple" method for coating plates, would be to use what I'd call a sort of "offset" system: A roller (rather large) sitting in a tray of liquid emulsion, which rotates, picking up a coating of emulsion, which is then transferred to a sheet of glass that passes horizontally along the top of the roller. (The roller would be "wet" with emulsion just prior to contacting the plate, and then "dry" (emulsion layer completely transferred) on the side that had passed the plate.)

I think this system would have a good measure of "self-regulation" of the coating process, but, be more trouble than it's worth for a very small hobby enterprise.
