A 20 Mpix Foveon is not enough for 24x36mm.

76 lp/mm at the sensor would be good enough for any lens except an Otus mebbe.

I've printed 24x36 images from my 14.7mp Merrill that look excellent when using Topaz Gigapixel AI (in Architectural mode) to enlarge the file. BTW, Foveon files uprez very well, much better than Bayer.

It would be interesting to find out if Topaz Gigapixel would do well with a fp L file that has been downsized to 1/4 original pixels.  The quality of these pixels ought to equal that of the Merrill, pixel for pixel, should it not?
