OBSERVATIONS: In the pictures, please compare the contrast, color saturation and sharpness of the fluid scan and the dry scan.
- Habit has conditioned us to accept what we get from dry scanning as 'normal', just as someone who needs prescription
lenses but does not know it, would regard his/her impaired view as 'normal'.
- Light plays on dry film quite differently that it does on film submerged in the optical fluid, which explains the greater dynamic
range, contrast, and colour saturation, etc. that we see in fluid scans.
- Histograms are shown below, which show an uneven rendition for the dry scan and peaked output while that of the fluid scan
shows greater continuity, better defined shadows and greater output in the dark regions.
- Imagine seeing the image bright and sharp through the viewfinder. (The fluid scan). Then, place in front of the lens a soft
filter or diffuser, or smear Vaseline on your lens: That is the dry scan.
- The optics of 'Dry' apply equally to slide projection and enlarging. Ansel Adams and company would have been overjoyed had
they discovered fluid enlarging. Fluid techniques can be also used conventional darkroom enlarging. -For the latter purpose,
a special fluid is required with properties appropriate for enlarger use.
