Woods, light, and drawing effect
A picture taken near CEA neurospin.
Non photo-realistic post-processing is a follows:
1) Editing of curves, in a non homogeneous way (more contrast and light in the center of the image)
2) Application of the non-photo-realistic filter "graphic-novel" (in the Gimp: G'MIC -> Artistic -> Graphic Novel), at different spatial scales in different layers
3) Blending the different spatial scales: lower frequencies in the top part of the image, and the reflections at the bottom; higher frequency near the center of attention
4) Light blue/turquoise vignetting (darken only), more pronounced in the top of the image.
