6. Crisis and formal-perceptual reading
Crisis:
The operation affects the visual grammar of the image: shape, outline, color, figure/ground relationship, legibility, recognition, and support.
The shape is maintained, but it creates passages at the moment of underexposing; that is, the outline and the relationship with the background mix and fuse together. Recognition is lost in that sense because the image darkens and the outlines are lost to define the image, or they are overexposed and the outlines are lost there too.
7. Final evaluation and artistic reference
Does this operation truly put the image into crisis or does it only function as an aesthetic effect?:
Yes, the operation puts the image into crisis.
Operation notes / what I learned:
It is a simple operation but of great utility since chiaroscuros like those of Rembrandt and Caravaggio are created, which help to control the image and give it volume. The richness of the crisis is high despite the simplicity of the operation.
