Sabatier Effect Information

The Sabatier effect, often called solarization, is a process of exposing a print to light a second time during development, thus reversing the tone curve for certain parts of the image. The result is an image that is part positive and part negative. Although attributed to Armand Sabatier, the phenomenon was first described by H. de la Blanchere in 1859.

Man Ray

The Sabatier effect is often strongly associated with the late-19th century and early 20th century photographer Man Ray. Man Ray produced many very well-known prints using the Sabatier technique, including the famous nude with violin style f-holes.

Darkroom Process

To create a print in the darkroom that uses the Sabatier effect, expose a print as normal in an enlarger. Develop the print as indicated by a previous set of test exposures. Rinse the print for 30 seconds, just enough to remove the developer from the surface, but not so long as to completely remove the developer from deeper in the emulsion. Remove the negative from the enlarger and put the wet print back in the easel. Reduce the enlarger aperture two stops and reexpose the print. Many people will do a test strip of the second exposure to check the level of the Sabatier effect and then reprint the image with changes in time on the second exposure to achieve different effects.

Darkroom Variations

There are many things that can be done in the darkroom to modify the Sabatier effect. One is to make the first print slightly out of focus. This will help control hard lines called Mackie lines. Changes in the initial development time can also achieve very different effects. Larger shifts between positive and negative can be created by diluting the first developer stage. Dodging and burning both during the first and second phases can help you create singularly unique images not possible with digital manipulation.

Digital Sabatier

You can approximate the Sabatier effect via digital manipulation by creating a second layer and inverting and adjusting the tone curve. Initially, the curve should look like a U with a V like peak at the bottom. By adjusting the blend and transparencies of the two layers, a Sabatier style image like the one below is easy to achieve.

Common Uses

Although the Sabatier effect can be used on any image, images with smooth gradations often work better for solarizations. "Do you need to understand digital photography methods that bring skilled photographers to where they are today? Well, The Top Secret Photography Techniques could support you out in doing so. To obtain spectacular images we primary need to look at some essential photography strategies. The preliminary one I am able to share with you is find out about light. You can discover all the things about photography techniques on , The Top Secret Photography Techniques. Anytime you discover about light and in what approach it interacts with the direct environment then your images will get better..". In some cases, photographs with intricate details end up with too many hard lines to benefit from this technique. Man Ray used the Sabatier effect in many florals and nudes. In some cases, the Sabatier effect can bring out textures in an image not initially noticeable in a standard print.
