Scanning Specifications (Raphael Project)

These are the scanning specifications that where used during the Raphael Research Project.

IMAGE TYPE SCALE RESOLUTION MODE FORMAT
35mm slides 600% 300dpi Colour RGB 8-bit tiff
120 (6x6 cm) transparencies 350% 300dpi Colour RGB 8-bit tiff
5x4 inch transparencies 400% 300dpi Colour RGB 8-bit tiff
10x8 inch transparencies 200% 300dpi Colour RGB 8-bit tiff
10x8 inch monochrome negatives 200% 300dpi B & W 8-bit tiff
12x10 inch monochrome negatives 200% 300dpi B & W 8-bit tiff
x-ray plates 100% 600dpi B & W 16-bit tiff

NOTE: Better results for scanning negatives have been achieved by scanning them as positives in Colour RGB 16 bit, and by modifying them with photoshop as follows:

  1. Image -> Mode -> Grayscale.
  2. Image -> Adjustments -> Invert.
  3. Image -> Adjustments -> Curves.
