After 2 years in Paris using my studio and other room spaces as a Camera Obscura (CO), I got another studio space (an old bunker) outside Paris which was in front a big park and high trees. 

I transferred it to CO and continued developing that technique (Sténogram). 

Here I went further in the process and developed positive images on large size negative paper. As well, I used chemicals like bleach & sepia together with some colour pigments to give another texture, colours and meaning to the images.
