Easiest hand mixed emulsion?
I am just getting into the alternative process, I have been looking at Cyanotypes which I will be doing contact prints with, I have also found that you can use them 'in camera' replacing normal film and paper negatives, they will of course come out at the same size as the camera format and you can't really enlarge them but I am thinking of getting a LF camera soon anyway. Using a cyanotype paper in camera will mean very long exposures ie a few hours rather than less than 10 minutes to do contact printing.
Thats not the question I want to ask though, I like Cyanotype because there are 2 easyish to get chemicals that won't kill you or explode and you develop in water (plus hydrogen peroxide if needed), this makes for a nice simple method which is easy and cheap to do. The main issue I have with film is the cost and issues around development due to the number of chemicals needed in some of the development processes - although I am thinking of doing a stand process with 100 + 1 Rodnal dilution which apparently works well. Also the film can get quite expensive especially with the larger format cameras, 35mm is ok as you get between 36 and 72 shots per roll, medium format you get about 8 shots per roll and LF cameras you get 1 lol
I am therefore looking for something that I can hand mix thats easy to use like a paper negative, I do like tintype but am aware of all the issues around that process mainly due to the fact you need to develop it asap and it takes a while to set up so thats why im asking if there is a process that is:
Easy to mix up
Easy to develop
Easy to handle (ie won't kill me lol)
I think the closest I can think of is probably something like salt printing, however that probably still can't really be used in camera, im not too worried about the lenght of the exposure as I plan to do landscapes etc with it, but what options are there for hand mixed emulsions that are used in camera?
Mark Osterman at the George Eastman House offers courses that are great! http://www.eastmanhouse.org/events/e...hoto-workshops

There is also a whole forum here on APUg devoted to just that idea:
Forum: Silver Gelatin Based Emulsion Making & Coating: Discuss hand made emulsions, emulsion making technology and coating. Papers and film.
As well as a very good website (run by an APUG member) devoted to the same:
Thanks guys, I put the post in this section as I wanted to try and stay away from dangerous chemicals and silver nitrate lol although checking out that photography workshop it seems that 'Physautotypes' seem to be spot on for what I am looking at doing: "The finished plate resembles a daguerreotype, but doesn’t require the use of dangerous chemicals: only rosin, alcohol, and mineral spirits"
Take a look at the 35mm Daguerreotypes class in July 2013 - it doesn't involve dangerous chemicals. I've seen some of the finished photos, and although small, are really great.

hi again m1tch
unfortunately there is silver nitrate involved, but it is pretty easy ...

heather still pops in from time to time, and is still active on flickr,
maybe she can give you the lowdown on physautotypes
good luck !

I will check that out, although what I might do to do some testing is simply buy an old box camera with an obsolete film size and then load a plate in.

Hmm the quest continues! lol I wonder if I created a negative on a cyanotype, then waxed or oiled it to make it transparent, then tried to use it in an enlarger - I have heard of it being done with paper negatives. Hmm I wish there was a simple and safe way of creating images in camera that doesn't require a lab of chemicals or certain expensive chemicals. Its almost easier to pay the extra and get a large format film and make cyanotypes like everyone else lol but thats just not as fun lol

No idea what's going to happen next, but I'm hoping it involves being wrist deep in chemicals come the weekend.
