Thnaks for the kind words, guys..
PyrocatHD is a nice developer especially for IR images, since it is hard to
predict how dense the highlights (leaves in this case) will become, you cannot
easily measure IR light. So if they become dense, the Pyro stain will become
strong also, which is a good thing in this case. The stain works as a soft
grade VC filter. So on VC paper you get an automatically softer/flatter
printing of the highlights.
Sometimes this effect is too much, even when using a grade 5 filter you
sometimes can get snap in. In these cases you can resort to fixed grade paper:
the stain density acts as added density to the silver density.
Added benefit is that the stain acts also as extra UV density, so the same
negative can be used for a platinum print, albeit that 4*5 is a bit smallish.
Best,
Cor

Very, very nice.
I have never used PyrocatHD on IR, but I'll certainly try after having seen
your results.

Ok,
As promised now for every body to see:

And the captions:
I shot these images in the court yard of the Boerhaave museum in Leiden, The
Netherlands (National Museum of the History of Science and Medicine). On a rare
sunny Friday afternoon, end of august. I used my last sheets of MACO AURA IR
film (aka EFKE Aura, equal to EFKE 820c IR film, since the aura effect is
simply not there, unless hard pressed).
I hope you enjoy them, as you can see it was quite windy, even in the courtyard.
best,
Cor
