This may just be a case of "upgrade-itis" when I feel my photos are stagnating, but I've had a difficult time trying to achieve that muted, pastel "filmic" look within digital. Of course nothing can truly replace film but I've become so accustomed to the workflow of digital. I currently use DxO Filmpack 5 and VSCO plug in for Lightroom to try to color correct my photos to look more filmic. I've gone through a few camera bodies in the past year or two, starting with the Canon T2i, then Nikon D800, and now Samsung NX1. Ironically, I find the best color reproduction I get is from the Sigma DP Merrill series of cameras. The foveon sensor on these are truly incredible and the images I am most proud of have come from these tiny cameras.
Just from my experience I feel the color from the foveon is so much more organic. You can still certainly tell it is digital, but throwing a Tiffen pearlescent diffusion filter really gets you close to a film image. All that being said, there are the usual marks of dynamic range, low-light performance, etc. but few benchmarks (that I found) for tonality and color reproduction. Maybe I'm in over my head, but I've been looking at the Pentax 645D. The CCD sensor of older medium format and 35mm cameras are supposedly more muted and close to that look I'm trying to get. The D800 files are solid but having used it for a few months, it's just clunky and not particularly inspiring to shoot with. The colors are also quite flat for my taste.
Any suggestions / advice / feedback would be greatly appreciated. Sorry for the long post. I'll post my flickr link for anyone wanting to scroll through my mediocre photos from these different systems.
