I am blown away by the results last night, and I remain inspired because so many possibilities just opened up. For contact printing if I limit myself to say 8x10 I could easily make silver wet prints without a vacuum frame. How cool is it to digitally proof your wet print? How cool is it to use digital post processing to make and develop the perfect negative for contact printing? Limited editions anyone?
I printed five 8 1/2x11's of a Monochrom night shot at 800 ISO 1/30 second using a Nikon 35/1.8 LTM wide open. The scene was a Central Park South crowd playing Pokeman Go in an outdoor public hot spot soon after the game got released. What makes the shot so remarkable is that everyone in this crowd shot seems fully immersed and so unaware at the same time.
So this was my first test: I took a tiff file that I had previously printed with K7 and explored what Piezography Pro could do. The first thing I discovered is that in the new updated paper profile library were three profiles for Jon Cone Type 5: cool, neutral, and warm.
I printed each curve separately to visualize the color gamut. In comparing the cool and neutral as they were drying, at first I was disappointed because they appeared too similar, but as they dried the difference became more pronounced, and I liked both. The warm profile I felt was too strong and the shadows were kinda brown.
Anyways it takes a while for the ink to dry, and one should allow for a full day of drying because using a hot air gun to speed up the drying I think does not give the best results, but I could already observe the blackest blacks I have ever seen. This morning I looked at the prints again: a wider dynamic range, smooth, highly detailed, and one has to believe optimized for making digital negatives for contact printing. Wow.
So the forth print I loaded in all three curves into my "Print Tool:" Cool; Neutral; and Warm. So now instead of printing with one curve, I'm printing with three, and I can adjust levels for highlights, mids and shadows separately.
The fourth print I made with the mids set up with equal portions of cool, neutral and warm, but I skewed the highlights to cool and the shadows to warm to create the most exaggerated effect of warm shadows and cool highlight split tone. The resulting print was a lot like my first bout with K7 where I blended my warm neutral 50% with Selenium at 50% exactly in the middle at Shade 4. This first iteration had too much warmth to my liking, so I ended up mixing in 25% selenium in my shade 3 to tone down the warmth further.
In the fifth print I toned down the warm curve shadows 25% and boosted the Selenium shadows from zero to 25%. The Neutral curve I kept flat at zero. The resulting print is a very close match to my K7 splitone.
So a 8 1/2x11 printed at 2880 DPI unidirectional takes 7 minutes. I see fine detail that favorably indicates resolution high enough to make contact prints of astounding quality, although prints bigger than 8x10 will likely require a vacuum frame for best results. For you guys that want to wet print small (8x10) this is for you.
BTW I kinda took advantage of Digital Silver Imaging a few years back. They had an offer that if one pre-paid $500.00 one got $1K worth of printing. I loaded up the truck and purchased $2.5K worth of printing. DSI makes silver wet prints using a laser as a light source. Anyways this was the state of the art 2-3 years ago. I had a handful of 24x36 inch fiber prints made printed on 30x40 paper that cost close to $500.00 each made from my best files made with my Monochrom.
So even though DSI uses a laser as a light source on big prints one can see a softness that gets projected via enlargement on the edges. This is the same one can see on traditional wet prints on big enlargements. Contact printing like a large format shooter is a workaround this limitation.
Anyways from my experience of printing large with Piezography K7 that the resolution kinda scales up, and depending on how perfect your image capture was that generally the larger one prints the more detail is revealed. In other words IQ and dynamic range seems to expand on the print the bigger it gets. I think I would need a 44 inch printer to get fuzzy, and then even that big it might not happen with the right clean low noise file.
Now we are talking in terms of doing what Salgado did with Genesis. Now it seems we do not need the best lab in Paris.
Anyways these are my preliminary findings. BTW I did compare print the dry number 5 PP print to a 17x24 (14x21 image size) K7 print this morning. Understand that the 1/30 shutter speed limited the IQ, and the lens was a retro lens shot wide open at night, but the tonality seemed the same and displayed the same smoothness and precision. Hard to compare resolution at this point, because clearly the smaller print is better.
Next test is print print number 5 bigger. Likely tonight. Understand that any comparision is limited by the use of older K7 curves, and that the entire curve library has been updated. To make a fair challenge I would have to make a new K7 print with the new K7 curve. Any judgement of PP to K7 should be reserved untill the new K7 curve is printed for a real comparision. Also know there was mention of a one-pass K7 as the next project. Hmmm...
