Scott,

I've not found Ware's formula to be that particular about paper but I
haven't used the ones you have mentioned. For the record I've used it with
Arches platinotype, Crane's Natural White Wove, Fabriano Satinata and
Bienfang 360 with success. I do remember that Fabriano Uno didn't seem to to
work well. I have a sample of Buxton on ice, perhaps someday I'll test it
against another paper.
All things considered I prefer the traditional cyanotype version better as
the Ware formula seems to compress highlights and has less over all
gradation for me.
> As a side note: I was using both spectral density (orange) and black &
white negatives created on an Epson 1280 using Dan Burkholder's methods. I
did notice that even though I lied to the printer (told it I was using photo
paper) when I used clear transparency film, the negatives came out very,
very thin.
Coincidentally, I had similar results using the physical density method and
the indexed color method outlined by D. Burkholder using Pictorico OHTF and
printing with a Epson C80. The colorized method gave a much denser negative
though. I just started making inkjet negatives two days ago and haven't had
a chance to print any yet. I'm also going to try making a negative with
quadtone inks foe comparison.
> I noticed that when I changed from gray-scale to indexed color that the
image lightened dramatically.
I noticed that too.
> The image also lightened quite a bit when I applied the cyanotype curve
and when I colorized the image to give it the orange color. Having a short
attention span to working digitally, I created a gray-scale image, inverted
it, boosted the contrast, increased the density and printed it on the trans
film. In short I got a much better cyan print (barring the above problems)
than I did using Dan's methods. Anybody have any idea what was going on?
FWIW, I used the instructions Dan has given in chapter 12 of his second bood
starting on page 130 - "How to Colorize a Grayscale Image". This method gave
the greatest density but not until I remembered to set the mode to color as
listed in step 6.
