B&W + Colour one sheet

Mick Incredible. What a great way to demonstrate colour printing. Just to make sure I have understood the process: It's all B&W at first. The bleach is pot ferri(?) then redevelopment in col dev. until satisfied. Does blix play no part in this? Once the print has been col developed to your satisfaction, what fixing, if any takes place?

Sorry if Qs are dumb but my chemistry knowledge is non existent. Thanks for sharing this. It's one of the most novel things I've seen on APUG

Wow, that didn't take long for you to look at.
I just realised I missed some little bit of info out.
You develop the paper in normal colour process, (in this case it was EP2) RA4 was the next and current colour neg paper developer.
Then I used my bog standard Ilford B&W paper fixer. You can turn the lights on here.
Then you bleach the print in colour paper bleach.
Then you fix the paper in standard colour paper fix.
What you have to understand is that Blix is something that was not the norm in older processes, at least not that normal.
This process is derived from an article by Patrick Dignan in the 1987 The Chemistry of Photography Volume II.
Robert Anderson then had an article in Perfect Colour Printing about boosting colour saturation and contrast in that 1990 publication. Both of these are Preston publications which published Photo Techniques.
Interesting what a bit of fiddling can achieve, eh?

By the way I also know very little about chemistry, I just read, then fiddle, fun things happen. Sometimes though, I just fiddle.

That's pretty amazing! Wish I was your student. I followed the link from your post about "how many tries to get a good print".

Janet, thank you for the compliment. I have found that standardising the mechanical parts of processing can, and usually does, enhance ones speed and chances in the darkroom.

I have yet to find a student not wishing to better their technique, especially in their early days of photography when enthusiasm is at an all time high! I also like to show them my mistakes and blunders as and when it's appropriate, this makes me far more human, I hope.

Melbourne isn't that far, how about a holiday?

Mick.
