Nikon's on-camera "miniature faking" tweak appears to increase the saturation, increase the contrast, and perform some selective horizontal/vertical blurring (with a falloff region) for a tilt-shift effect.
There are more robust solutions for mimicking the tilt-shift DoF than the one available through this filter, so I would rather use those. But, I can't quite replicate the saturation and contrast effects on my end.
Here's an example; Original on the left and "mini faked" on the right. Click to expand images.
What process needs to be done to mimc the contrast and color saturation portions of this filter?
