I just want to start out saying that I'm drawn to abstract photography. Double and multiple exposure, Lomography, film soup and and editing tools that give me abstract looks to my photos. I am far from a professional photographer and still in my experimental stages. My latest project has been with film soup.
Basically film soup is 35mm film that has been soaked in different liquids then dried and shot. Film can be souped before or after it is exposed. They both come out the same. I have only used film that has been souped before but I will soup my own soon and will post pictures and recipes after. For my first try I used souped film from a well respected maker of film soup Hanna at Hannalogical. She sells several different styles she makes on her Etsy store by the same name and I will put links at bottom of this post.
The second most important thing to keep in mind using film soup is that most labs will not process it as it can ruin their expensive chemicals. Some people use the old chemicals after doing regular films or as in my case I sent mine to Film Lab 135. Owner Amy Elizabeth does a great job. I don't know of anyone else offering this service. I'm sure you can do it yourself but getting great results is another thing. I prefer to send it to Amy as she has the experience with it.
I shot 4 rolls of different recipes and I must say I love the results. I haven't quite figured out what scenes work best with it. I shot fall colors, landscape, architecture, sunrise, sunset. I can't say its better for one or the other it all depends on what you like.
I like the randomness of it all. You don't know what you are going to get. I have some photos that show light leaks etc. I would really like yo try it some more. I have a couple of rolls of pre souped left and I will do the next rolls myself. I've heard of people souping negatives after the have been developed which seems like an easy way to do it. I will post more after my next experiments with it. I would love to see what you come up with in the comments. As always with photography have fun with it!
