Slide recording resolution
I would like to use a commercial service to record digital images to
transparencies, for use in a stereo viewer. Does anyone know what typical resolution (PPI) these services record transparency slides at? |

That's OK for printing, but a slide is likely to be blown up 30, 40, 50 times. I would consider 3-4,000 ppi to be a more reasonable figure. A good consumer film scanner will output 4K ppi. A drum scanner will do even better. Bob Williams |
