Digital BW, The Print

Speaking of print fidelity - based on a completely unscientific approach and merely judging by comments made by people, Piezography prints are in a different league compared to ABW.  I use Piezography Special Edition inks on matte papers, so I can't comment about the glossy inks.

One interesting thing that I noticed is that people normally refer to my ABW prints as "pictures" or "images", but they often use "art" and "three-dimensional art" when they talk about Piezography prints.  The "three-dimensional" comment is actually very common for Piezography prints.

On two separate images, different people asked me if there was a "special effect" or a "trick" that I had used.  One image had a very light gray roof easement on a 250-year old church (it was light golden in real life).  It looked shiny and reflective on the print, just the way it was in real life.  The other image was of a black marble statue reflecting light from the overcast sky.  The shiny polished marble was glistening, almost glowing on the image.  Both of these were printed on matte papers!

Jon, I would add another criterion to your list: plug & play vs. tinker.  If one's primary goal is to concentrate on producing high-fidelity images being assured that the inks will deliver to one's vision, Piezography is a great choice – it is plug & play, it allows you to get great prints right after installation.  You don't need to spend countless time, ink and paper to achieve your goals.  I don't have anything against tinkering in general; it's just a matter of personal preference.
