“Positive” Paper

We print from a negative and the print is positive, right?

We print from a color negative and the print is positive; we print from a color positive (a “slide”) and the print is still positive.

If we use b/w paper in a pinhole camera, we get a (contrasty) negative print; most often, we contact-print that paper negative, in order to generate a positive print.

Paper designed to make a (positive) print fromĀ a (positive) color slide, placed in a pinhole camera, would make a unique positive print, right?
