hi LMNOP
aside from getting scans of your negatives made at the lab that processes your film
you can also take a sheet of photo paper, regular old stuff, and put it with a negative on top of it
in the sun under a piece of glass ... you can get fancy with a contact print holder but it isnt' necessary ..
after a while, ( depends on the sunlight and blue light ) you will have a photograph printed on the paper
that you can scan like a regular print ... you don't need any chemicals, and you only get once chance to scan it
because it will turn greyish with every pass of the scanner

you can do this with paper in your camera instead of film too, it takes a while to get an image but you get one ...
also, you can make cyanotypes, super fun, super simple takes 2 chemicals and when you wash it
nothing is washed away but iron complexes so it is really kind to the environment if you worry about your footprint ...
you can find premade cyanotype paper called " sun print paper" sold at crafts stores, or you can make it yourself,
bostick and sullivan sell kits and the photographers forumlary too, it just takes paper and a paint brush ( foam is ok or a hake japanese brush )
if you don't like blue prints you can soak the print in a teeny bit of baking soda or washing soda to bleach it ( take the blue out ) and dye in tea
emil schildt ( gandolfi here on apug ) is a master of this process ( and a whole slew of others ) if you need inspiration
least effort low tech is paper in the sun you get chemical free positive prints ... the cyanptype takes a bit more effort but they can last forever ...
2 samples attached are both scanned sun prints made with photo paper and a negative
have fun! ( and good luck )
