These Kodachrome shots look like Foveon images.

I saw these on the Pentax forum too. Kodachrome, when properly exposed, provides a transparency with richness, color and contrast that is unmatched by any other film or digital camera. Many abandon Kodachrome when Fuji Velvia became available with its garish, wet paint look. I never really liked the film although it was highly successful for Fuji. The only films, in my opinion, that came close to Kodachrome would have been the original Fuji 100 and Provia.
