Collodion seems to have a more unique signature, especially if making positives. Gelatin dry plates are a bit closer to modern film. Orthochromatic, and definitely a bit more hand-made than modern film, but the prints still don't seem to have the same impact as collodion. They do have a nice old-fashioned look about them. That's my take it, anyway. YMMV
If you go to thelightfarm.com you will find a lot of information on gelatin dryplate making.
You can see what I came up with by clicking on Galleries, then click, Dry Plate and Artisan Film Gallery. Mine are the ones by Kevin Klein. Clicking on one of the pictures gives a description with a link to the emulsion making instructions.
Or are you looking for Collodion dryplate.
Hope this helps.

dont even think about messing with making dry plates until youve had years of work in wetplate and understand the chemistry and how it works. almost no one today is capable of making good dry plates 'at home'.
Ray, are you referring to collodion dry plates? I believe that the above comments are specifically referring gelatin dry plates, which seem to be a whole different animal.

Yes Ray, you are right. It is best to have good working experiance in the wetplate field to better understand what you are working with. On the otherhand, if one was making gelatin plates first, that would also provide some usefull knowlege as far as working with the materials and pouring technique and familiarizing ones self with the materilas at hand.
Most if not all of us had no idea what we where getting into with the wetplate but did it anyhow. The materials used in wet, dry or gelatin, are all very much the same except for the collodion and gelatin, the manipulation is only diferent.
I have done very succesful work in both dryplate fields, one is an extention of the other.
You have to start some where.

Kevin, what kind of exposures do you get with dry plate? I mean, in relation to wet plate... like twice as fast, three times, etc. as a collodion positive?

The exposures for a collodion dryplate are about 3 or 4 times that of a wetplate, some are a lot more.
It depends on what dry process you are using, Tannen is one of the most well known versions but I like to use the Coffee/Sugar (preservative), it is about twice as fast as tannen and the preperation and development prosedures are exactly the same with both.
I made an exposure in overcast weather with full open portrait lens (f:4) 6 seconds, turned out great.
Sorry if I was unclear...I was wondering what kind of exposures one could expect from gelatin dry plates. I know that there is some reference on TLF page, but not really in comparison to a collodion positive or negative.
