Yes, in 35mm this film is called Vericolor Slide Film. In sheet film it is
called Vericolor Print Film. I think what Michael wants to know is, does it
work well and is it worth using?

I have used this film very effectively and anyone can if they have a method
of copying slides and of varying the color of the light source, say with a
color head (this is what I used, upside down on a stand) or color printing
filters. You don't have to develop it yourself, you can take it down to your
local lab because it is a C-41 film just like other color negative film.

If you just want one or two slides I would say it is better to use slide
film, but if you know you are going to make many copies or if the lighting
is very difficult (either determining the exposure or the color balance is
unusual) then using negative film and Vericolor Slide Film is actually
superior. This is because you can easily modify the color balance and
exposure when you are making the slides, and these slides are actually
superior  to copies of slide film (although not necessarily to an original
slide, because you are still using 2 lens systems, instead of one, as with
slide film).
