0730331879 shows the selfportrait of a digital camera sensor.
It consists of experiments dealing with the phenomenon of Hotpixels.
Hotpixels are spots on the sensor with an exaggerated sensibility for incoming light.
The image 0730331879_N1_LB emerged from a time exposure with a completely covered lens.
Therefore the view on the outside world is blocked and inner processes of the camera are unveiled.
Emerging Hotpixels remain as the only element of the image.
They generate galaxy-like structures that turn out to be random compositions of red, green, blue and white squares.
