Re: Myth: giving BO a fair try

After reading all the posts,no better then giving BO a fair comparison to
quad. So I got a good image and printed it side by side using MIS FS Neutral
on a single sheet of EAM paper( Epson 980). BO was according to Clayton's
recommendation found in his webpage. Result?

No big surprise. The quad is absolutely smooth,no dots anywhere,perfect
gradations. The BO is coarser, shows the dots that can be seen from a foot
away,MAINLY if you're looking for it,and seeing them side by side. Is it
bad? No,it\ufffds different. Clayton calling it "digital Tri-X" seems fair,it
really resembles it. I wouldn't use it for a rich,detailed landscape,but
would find it acceptable for street photography,for example. Just like I
would use Tmax 100 or Provia 100 for the first,and could use (though I
dont't like the grain!) Tri-X for the second.
In conclusion: Can you get prints as smooth with BO as you can with quads?
No way. Are they unacceptable? No,if you know what they look like and live
with the difference...

Sorry, that's just theory.  I _know_, from real experience, that I can
print both high and low contrast images with the BO technique and get
beautifully rendered prints that match the digital images accurately.
It's a fact I can demonstrate.
