Unfortunatley the 24 hr delay after iodisation was a mistake with this paper, see the scan with transmitted light, serious fogging could be seen emerging after exposure
15 min exposure bright day blue sky f/6,3 whole plate
Winther's tannin process with Sumac extract
Pre-silver brushed 5,2% AgNO3, dried iodised in 4% KJ for 10 min followed by 2 water baths of 10 min each (pure water) blotted off and dried
Sensitized just before exposure with sumac extract 28 drops, AgNO3 14% 7 drops, gl. acetic acid 2 drops made double.Exposed moist in a glass sandwich.
Developer brushed and sprayed with 25% alcohol for 1 hr 10 min
Developer consists also of sumac extract 28 drops, AgNO3 14% 7 drops, gl. acetic acid 2 drops made double. After brushing sprayed and left wet face up under cover, brushed also just with Sumac extract saving the silver nitrate for later to boost density.
Short wash before 2 x 10 min hypo and 1 hr running water bath
Canson Marker paper was pre-silvered and iodized the day before exposure and processing.
The paper behaved well when prepared pre-silvering and iodisation on the same day as exposure and processing.

The "Rotation" is when some of the NATO Mission members are due to go home and their replacements arrive.
A time of high emotions,carefully surpressed.
This group have just arrived and are going through the necessary administration, collecting their security passes, etc, etc. It was well organised this time - but took place in about 35 degrees C...
Mordancage is kind of hard to explain. Essentially, it takes your b&w image and allows you to manipulate or remove the purest black areas. You can also create these lovely 'veils' of black but again, hard to explain. Once I have a successful image, I will scan it in and show you what I mean! =)
Edit: Ah, I should probably explain what's going on, lol.
1) I placed my print (after it's been soaking in water for a bit) in the mordancage chemicals. It's essential an acid that will bleach your print.
2) The image after it's been bleached for 3 minutes. I left it in for an extra three minutes after this shot.
3) Then I placed it developer so that the grays and other tones will come back. The blacks should be visible and able to be lifted off the print.
You can either completely remove the black or you can move it around. It creates really cool effects.

Trying out the new lasercutter at work, I made an enlarged version of an old growth form. This is cut from 6mm black acrylic - works pretty nicely as a heat mat.
Reworking the Tentacles piece (aka Nebulae). Should have a realtime version working soon. This one does a bunch with the pixel array for the entire frame so it runs at about 1fps.
I watched the Lion King in Spanish yesterday, so from now on my cat will be called "Seem-ba!" XD
Cross-process FTW. Or so I hear. :)
