For anyone who processes and prints there own film, experimentation is a great way to produce new images. Many of you will be familiar with solarization of prints, or Sabbitier effect, but solarizing your negatives is another tool.
The first rule of thumb is that simple images tend to work best, small still lifes, flowers, nudes, etc. I generally use small 35mm film strips, cutting 5 to 10 frames out of the camera in the darkroom. Load onto a reel and process normally. Halfway into the development process, remove the film from tank and reel in the dark. I shake the strip a couple of times to remove liquid. Lay flat and expose to white light such as a 60 watt bulb for 1 to 10 seconds – you need to do some experimentation with your film and developer here. Turn out the light, return the film to the reel and the tank and complete the regular development. Stop, fix and wash normally and prepare to be amazed.
