B&W downsampling vs. scanning at equivalent resolutions
B&W negative images downsampled from a scan made at 8000 samples per inch are smoother and exhibit tighter grain than scanning directly at the respective resolutions. See Section A from the same negative.
Each section represents a 1.27mm square of film.
Mouseover the images to compare
downsampling and direct scans overlayed.
Section B
• The left column contains a section of the original 8000 spi scan and two versions downsampled from it.
• The right column contains sections from direct scans.
• All sections are unsharpened and unfiltered.
• All sections are displayed at actual pixel size.
