Well, one thing to really do is look at the resumes of some of the great photographers of all time and work your way backwards. I saw that, because artistic photographers often partake in pay-jobs and end up being totally outside of the realm of "art". One of the biggest things I've seen is the resurrection of techniques prior to film as you know it today - namely on sub-straits like tin/glass and low ISO below 1 .. yes ISO --> 1 <---. That might be a start.

Landscape/art photography with large format negatives (4x5 and above) I understand...we still don't have practical digital cameras for that.

But what is being done with emulsions of ISO <1?
