"Slot Canyon #7" ~ Gold toned Kallitype
My apologies for the dead spot. House repairs took up last week. I'm old, things take time. My wife and I will be in San Diego most of next week, so there's that. For today however I continue the print series of the Slot Canyon images. I have been working with a theory that I have been testing with these past three images. As I wrote in the book on Kallitype printing, increasing the amount of solution necessitates increasing the print time to compensate for the deeper penetration of the silver solution. That has been tested and proven out.
Secondary to that variable is the variable of lengthening the density range of the negative, theoretically increasing the theoretical "depth" of the print image. Turns out, that theory has a boundary, and that boundary was crossed with these last two test prints. The added solution amount wasn't needed, and secondly and far more important is that increasing the print time to print down the increased densities has the same affect on the Kallitype image as it does on a palladium print image; bronzing in the shadows. I watched this happen during the development of the print, what began as a dMax black lightened up to a deep gray in places where the black would have been deepest.
The take away from this is to return to a reduced amount of solution, and drop the density range from my Kallitype <curve>, which is quite hot, to my Na2 <curve> with fits well for Na2 prints and gum prints. It is also a very good curve for the Kallitype, with an 8-9 minute print time, compared to the 13-17 minute print times of the denser negatives. Finding the sweet spot is the point of the exercise. I believe I have found it. The posted print was printed using the negative with the higher density range, with a print time of 17 minutes. Another slot canyon image, same densities but a negative of lessor densities prints at 8-9 minutes, depending on how much of the white one wants printed in. In this print the highlights remain in zone 8, which is not what I am after. A good teachable moment for me.
What can be seen with this print image is that the tonal range is extended. What tends to happen is the middle tones, the grays, get compressed when the density range is too great. Another downside. This print was made on Hahnemuhle paper, developed in a sodium acetate developer and gold toned. I'm using the gold chloride 5% with citric acid toner formula. This will be reprinted soon.
