Why BlueNeg?
------------
This set of images is collected for studying the research problem of
restoring the corrupted negative films. Due to the physical nature of
negative film, the red, green, and blue light-sensitive layers are
located differently inside the negative film. Therefore, the rates of
deterioration of these three layers are different. I found that the
blue channel is relatively vulnerable compared to the other two channels.
Because the blue light-sensitive layer is on the outermost layer on
the emulsion side. That is, the deterioration rates are heterogeneous.
This characteristic is inherited from its ancestor, i.e., storing the
three color negatives (R, G, B) on three separate glass plates by
Prokudin-Gorsky.
Since the blue channel is more vulnerable and the other two channels
are relatively well-preserved, this means we can restore the blue
channel by exploiting the retained information from the red and green
channels to restore the color photograph. This is especially sound with
the latest AI technologies.
Unfortunately, most existing photo restoration techniques are
developed based on printed photographs, in which the nature
of deterioration is different from that of the negatives.
This is why I have scanned a collection of negatives I have shot
during 1980s to early 2000, for this research.
