Multiple toner aims to produce the effect of a range of chemical processes that can be applied to black and white prints. The tones used are generic, and the black and white conversion approximates the spectral response of panchromatic film.

The sepia toner is based on an existing effect, and closely matches the look of photographic prints that have been compared with it. The selenium toners have two presets because the actual colour produced is seriously affected by the chemistry of the paper used. Bottom line: these colour values have been obtained empirically. Even with the best care and attention given, how well the results match can only be subjective.

I've had to rely on on-line reference images for the gold toner. As far as I'm aware I've never actually seen one "in the flesh", so to speak. I opted to emulate a combination of gold/sepia, which is apparently a reasonably common toner process. The blue-black of pure gold toning didn't looked as uninteresting.

Copper toning can vary from the reddish tones that you see here through to quite green or even blue depending on the print's age and how it has been stored. I just picked a colour and contrast setting that had about the right look. I've based the blue in the iron toner on the blue you see in blueprints, because the chemistry that produces that colour is identical to the chemistry in a treated photographic print.

Multiple toner (MultiToner.fx) aims to produce the effect of a range of chemical processes that can be applied to black and white prints. It emulates sepia (silver sulphide), selenium (2 variants), gold, copper and iron toners.

You will find the effect here and installation instructions here.

In an attempt to control the size of this thread it is now locked. If you find a broken link or an effect that doesn't compile or run correctly please post as much information as you can about the problem in the Custom and User Effects feedback thread. It will be attended to.

The fact that this thread is locked does NOT mean that it is no longer active. There will doubtless be additional effects added and possibly even others removed. It's just the feedback that has been separated out. In fact even if you just want to talk to us, use the Custom and User Effects feedback. We'd appreciate hearing from you.
