Yes, I have compared it. There is no sharpness difference to speak of.
Emulsion to emulsion has some disadvantages, since we are contact printing
high-density (4+) dots. There is no light going through the dot! This means
exposure and filtration make little difference. By having the film thickness
as a ¹spacer¹, some diffusion is helping to get some exposure and contrast
control back. But it is too small to lose visible resolution. Yes, I¹m using
the enlarger as a light source.
