For slide film, I don't know if it develops directly into positives or
if there's another step involved where they basically make a negative
of the negative and stick it into a slide case. I never developed
slides at home when I was playing with developing my own film back in
the 70's.

One of the slide films, Ektachrome?, develops as a positive; it's
a complex process because the dyes are in three layers. WYSIWYG.
