You can always blur your Foveon image to look like CFA. But don't expect a CFA sensor to invent data point it does not have.

I wonder if you can tell me how to use unsharp mask to selectively blur out detail finer than 0.4 pixel radius without touching any of the other detail in the image.

So far as I can tell, unsharp mask will sharpen to a radius but will not "unsharpen" to the same radius.  To do that I would have to set the % slider to negative values and it doesn't go lower than zero.  This might be entirely my own misconceptions about unsharp mask and they are getting in my way. I need some help here!

Thanks,
