Solarization
Solarization ( the " Sabattier " effect ) partially reverses the image , by fogging to white light during processing . You can fog the image during enlarging on bromide printing paper , by briefly exposing it to normal lighting during development . You will achieve better results by printing on line film instead , fogging this , and then enlarging .
- The exact effects of solarization are not predictable you will have to experiment to achieve a controlled result . Some tones on a solarized print are rendered positive , some negative . A thin line appears around the boundaries of adjacent strong black and white tones in the solarized image .
Print from a normal negative
Most tones are eliminated in a solarized print , and a white edge line divides areas of white from black . Consequently , an image like the one shown right , with strong interesting shapes and sharp detail , is particularly suitable for solarization .
Making a solarized print
1. Make a series of contact prints on to 4x5 ins line film to discover the correct exposure . Contact print the negative at the exposure you found correct .
2. Half way through developing the print , place the tray on the enlarging easel . Switch on the enlarger and fog the film for the full exposure time .
3. Complete the development time and fix , wash , and dry the film . If the image is light enough , cut the film to 35 mm wide and enlarge .
4. If the image is dark contact print the film on to continuous tone film . Process in print deve- loper to give a less dense image , suitable for enlarging .
Print from solarized film
The print , right , was enlarged on to normal grade paper from the solarized negative below . Notice how areas darker or lighter than the main sub- ject can be either negative or positive . The white sky , for example , has become as dark as parts of the tree on the solarized print .
