[filmscanners] Re: 3 year wait



Hi Laurie,

Thanks for the rundown on your research on film recorders.

You inspired me to dig up my file on film recorders. What I can fathom
from the literature here, the "resolution" numbers translate to a round
down of the total addressable pixels across the long side.

What I show is a 2K image is 2048 x 1366 pixels
a 3K image is 3072 x 2048 pixels
a 4K image is 4096 x 2732 pixels
a 6K image is 6144 x 4608 pixel
an 8K image is 8192 x 6144 pixel

These are exactly a 3:2 ratio, which is also used for a 35mm film frame.

So, this is basically the number of pixels in the total image,
regardless of the magnification involved.

I don't think it directly relates measurable lines of resolution, but to
addressable points on the screen, sort of like Epson printers have 2880
x 720 addressable points per inch, but that doesn't indicate the
resolution of the image.
