OK...sorry if this thread is a waste of space, but I'm in disbelief.
I had a big order of paintings to do, so I've only used the z3100 so far to print some paintings on matte paper.
Printed a friend's nature photos on glossy paper and was really impressed with the results. Decided to give the z3100 a test. I have a file of a photo made by a friend of mine (on film) where he used a long exposure at night. If you've done or seen this, you know the sky (and other areas) usually produces as gradated shades of blue. On my Epson, I was never able to get a satisfactory print of this file, as the gradated shades of blue resulted in banding.
I did not expect this to change much on the z3100.
All I can say is "Wow!" The print appears to be just about perfect continuous tone and perfectly matches the image on the monitor. I am in awe!
I still use my B&W darkroom regularly and I can't wait to see some of those results.
