Originally posted by dtmateojr Landscape photographers layer multiple filters in front of their lenses. It's not something new.
And because those filters are on the front of the lens they will be out of focus, what you are suggesting requires a high degree of edge alignment between areas of high and low contrast - which means you would have to place the filter very close, if not directly on the sensor. If you place the filter further away form the sensor the filter itself will be rendered out of focus which will cause contrast halos, the result of which would look like a poorly blended HDR:
The image would look like this:
( not my work, thank god)

Any additional piece of glass you put between a lens and a camera is going to alter the characteristics of the lens itself, in a majority of cases the effects are reduced resolution and contrast. In the worst cases increased astigmatism, chromatic aberration, increased amounts of LoCa, coma, vulnerability to flare and amplified field curvature.

I take it you have issues with colour photography?

Cameras go behind lenses. Exactly when did I say cameras are stupid?
