Slide projection is the field where film has the greatest advantage over digital.
With a very good quality projection lens you can fully exploit all the detail on film and project it onto the screen (we've tested that several times). No significant resolution loss and grain enhancing like with most scanners.
And very cost effective: A huge, brillant slide on the screen cost about or less than 1€, a print of the same size cost more than 100 €.
If you want your pictures great, impressive, sharp and brillant, and you don't have a fortune to spend, slide projection is the way to go.
And much better than digital beamers. In digital projection you pay 7000€ for a 24 MP D3x, and then another 7000€ for the beamer to smash down your 24 MP to extremely low 2 MP (and that even only in horizontal direction, in vertical direction it is 40% less).
We've compared the 7000€ beamer class with slide projection in a direct comparison: No competition, no chance for the beamers at all. Much much better detail and color rendition with the slides.
With slides you feel like being back in the scene at the moment you shot it, it's so real.
It's a "time machine".
