first ... would you be making the emulsion for your gelatin dry plates yourself ( lightfarm.com )
or using useful information found in the emulsion making forum here and elsewhere, or will you be
using pre-made emulsions ( liquid light, maco, foma, or the stuff from the costa rican coffee arts
( http://www.costaricacoffeeart.com )
i ask because there are steps involved in making gelatin emulsion that some may say are time consuming ...
there is a whole art in making silver gelatin emulsion,
and some just bypass the whole thing and buy the bottled stuff. i have done both,
and find myself not having the time to making the emulsion myself. it isn't overly complicated
... i made it in college in the 1980s when there was no internet, just photo annuals from the turn of the century,
but it is time consuming ... and you have to pay attention to details ( like everything else .. )
the most time consuming hassle part of making dry plates ( if you buy the emulsion )
is cleaning and subbing the plates before you put the emulsion on them ... not much of a hassle
while i haven't done the other 2 processes you have asked about ... i have read about them and i have teetered close to doing both of them.
it seems the time consuming part of the dry collodion plates is making the emulsion ... and coating the plates ...
( not many more steps than making dry gel plates )
the hassle of using wet plates, is sometimes in cold or hot weather it isn't as easy to make plates,
the plates have to be processed right away when the plates are still wet ...
and your chemistry and silver bath might go wonky depending on how many plates you have made &c
wet plate users can probably answer that question way better than me ...
it seems to be the easiest of the 3 processes though .. just collodion, silver nitrate and the developer/fix
the others seem to be more time consuming because you are making an emulsion, rather than sensitizing a viscus fluid.
unlike wet plates, dry collodion, like gelatin dry plates, can be stored for some time after they are made, and can be used without problems in cold or hot weather.
if you get a subscription so you can view the apug gallery,
there is a subscriber who goes by the name "hermit" who has some examples of dry collodion plates the he has made. they are cyanotype-printed so you can kind of get an idea of what the plates are like
you can probably poke around here and the light farm to see some dry plate prints look like
... i haven't really scanned any the dry plates i have made.
i have plans of making some in the weeks to come, and if i actually do, i will try post the results for you.
they'll be made using liquid light though, not emulsion i mix myself ( sorry, i'm a lightweight these days )
have you found the silver sunbeam yet ?
it might be helpful too so you can get an idea of what the process from start to finish is all about ...
hope was some help ..
good luck !
