Yes, MF Provia (and its super-trooper stablemate, Velvia) sure impress.
You don't need a projector. Just a lightbox left on all the time to repeatedly put a smile on your dial!
The reason you got such impressive results is that you exposed Provia in conditions which it, like Velvia, favours the best: diffuse (flat / overcast) illumination. Everybody knows (and should know) what Velvia and Provia can do to a good scene in point light it is absolutely ugly and intemperate; it's not clever or smart to do it that way. Take it out on a rainy day and fine greens and reds to play with: a polariser adds extra 'gasp' factor in the right conditions: forests and scenes where the sky is excluded work best. I never ever step into a rainforest without a polariser on Velvia. No pol needed for sunrise or sunset as the resulting scene can come across and very flat and lifeless.
Provia 100 is used in my trusty XA which almost trumped the images from MF! But MF had other ways of trumping Provia ... with Velvia!!
