SUBCONSCIOUS WITHIN (2017) 摄影 由 Roberto Colombo

The rationale of this work has three main points.
1. Explore a field, the abstract. Today many abstract photos are result of an important postproduction. I want to avoid it. My project is an attempt to abstract without manipulating images.
2. Back to the origin. My goal is to get back the original meaning of the word "Photos Grafeo". (Light writing).
3. Innovative technique. I am a chemist and for several years, I've been experimenting with different ways to do this. The colors are generated by the flash / lamp light across a colorless transparent liquid film stretched vertically on a metal structure. The liquid film is made by mixing water, sugar and thickener. I do not add any filters, pigments or colors and I do not use any artificial effects in post-production. Pictures are what the camera sensor records. I can try to modify shapes and color effects by adding small quantities of always colorless alcohol, glycerin, surfactant ... and so on, but the light decides where and how to do it.
