You quickly find that the enlarger can make the image even more *out* of
focus, but there is no purely optical way to make the image more *in*
focus than it is on the negative. Not even with all the king's horses
and all the king's men :-) [I don't thinks it's technically an
entropy example, but it acts like one.]
The darkroom process is classic converging lens optics with a "real
image" produced. If you do some ray diagramming you soon see why a lens
can't reconstruct a sharp image from a blurred negative. With purely
optical 2D rendering, the best you can hope for is an accurate rendition
of the immediate source. It is truly a "garbage in, garbage out"
process.
Best wishes,
