Re: Cyanotype

I made several test prints with the coloring from 0,10,10,0 thru 0,50,50,0 in steps of 10. I found that with the higher values for M and Y, the print was impossibly contrasty. I had no mid-tones at all. Part of it might be the Lenox 100 I am using. I had very different values when I was using Fabbriano Classico, which I can't get any more. I'm finding the Lenox 100 is a bit softer in the details than I would normally like, so I may continue to seek out different papers.

Actually, what I did for the test prints was to take a step image from 0 to 100%, make multiple copies of it, and apply differnt Dmax curves to them from 0.5 to 1.5 (by 0.2), and I placed them all on a single 4x5 image. I then took that and applied different colorizing to it, and then printed them 4-up on 2 8 x 10 sheets. From that, I came up with the Dmax curve of 0.6 and coloring of 0,10,10,0 as giving me the best range of mid tones. By doing them all together, I was able to eliminate the variability of exposure and development.

Someone suggested a longer exposure. It might help for this image, but for some others, the exposure was dead on. A longer exposure was overall much too dark.

This image is one of a series I am printing of several Cape Cod lighthouses. I'll be having these in a show this weekend, so I'll see what the feedback is from non-photographers.

Or, perhaps less contrast in your dig neg curve's highlight area. Look
at how quickly the zone 6 to zone 7 sky graduates to near paperbase.
You mention the neg is colorized "0,10,10,0". That is unusual. The
"norm" would be "0,55,55,0". There is nothing wrong with being
"unusual", in fact with this group it may be the "norm"! I'm just
curious why you chose that color for your dig neg??

Fine image, it really says "New England".
