I guess the reason I'm debating on it with you so much Roger, is that MGIV is commonly noted as having fairly ineffective response to selenium toners. I just found it surprising that you noted the paper for it's response to KRST and how most people note the complete opposite.
The toner response I'm taking about is not polywarmtone style satanic red. I'm talking balanced semi-brown/eggplant/greyish/etc.
That being said, I enjoy the debate, as I'd much rather be debating about this than CMOS vs CCD.
Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
