Chardonnol - Chardonnay as Developer

What gave me that idea?!
Well, very simple, Dirk posted a very interesting article (and video) about developing photo-sensitive paper with red wine and some other stuff.
Have a look: http://www.caffenol.org/2012/06/20/wineol-red-wine-developer/

This inspired me to research a bit myself, which brought me to this page:

Interesting! It seem that chardonnay actually produces the most caffeic acid. Now you know why this white wine always caused you problems!
Don't drink it! Use it as developer!
Some more interesting reading on the topic can be found here:

Right, let's go to my first ever experiment using chardonnay as developer:

Chardonnol

Recipe:
  • 0.5l cheap Chardonnay
  • 3/4 tea spoon ascorbic acid => measured pH 4
  • 2 tea spoons washing soda => measure pH > 11 (maybe 1.5 tea spoons washing soda will be better)
The soup was brown by now.

X-pro development

I developed a regularly exposed Agfa vista plus ISO 200 (C41 color negative film) for 16 minutes in a Jobo Universaltank 160 Mod.4.
Agitation during the initial 30 secs, than every first 10 secs of a minute.
The result was very very faint, somewhat like the experiment I did with Caffenol-STD and a 10 minutes development (see previous post).
Here is a high contrast frame (dust in the darkroom, dust on the scanner, I even seemed to have managed to scratch the film). One image reflects the file that my Epson V370 produced, the other image was a result of playing with curves in the GIMP.

Unlike with the under-developed example shown in the previous post, I was unable to recover any color information from the negative. Maybe the development was even too short for this.


I figure, Chardonnol would be a very good developer for stand development, in particular seen the fine grain it produces. Will try 45min with this recipe next.

Here is another example, low contrast now:

curves, brightness and contrast adjusted

This time, I operated at the very limits of image reconstruction. I guess, the vertical lines are actually inside the film material, now visible due to the enormous push by the scanning software and my GIMPing.

Printing those frames (by means of an enlarger) could be a challenge. Asks for grade 5 paper, I guess.
