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.

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

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 * Added: 02-09-10 20:56 Keywords: MACO Aura 4x5 IR EFKE IR * Location: Museum Boerhaave, Leiden, the Netherlands * Equipment Used: Linhof Techika III, 90 mm S Angulon at f22 * Exposure: 2 ASA, 70 red filter, 5 seconds * Film & Developer: MACO Aura 4*5 IR PyrocatHD * Paper & Developer: Ilford MG FB * Filter: 70 ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
