Hmmm... sounds interesting! Can you provide any details of your method?
To my way of thinking (and obviously with seeing any examples) this sound more like you are staining the paper and not truly toning the image. Toning an image, to me, is shifting the tone of the greys and blacks. I.e. you are affecting the image not the paper it is printed on.
Either way, I'd be intere
Yes, you’re right, it’s rather staining the paper than toning the subjects of the photo.
I use food colouring what you can find in any supermarket.
As with vinegar I use cider vinegar and white vinegar. White vinegar is better if you don’t want the vinegar to take any colouring effect. The coffee is the cheapest powder coffee what you can get. I use it only if I want to boost the orange or brownish stain.
The mixing is quite improvised, I just go with my gut feelings and check the colours by eye and continuously keep in mind that the vinegar will dilute the colours so I always mix a deeper tone.
Without the vinegar and/or coffee the food colouring doesn’t do too much only a bit of layer, I just tried it once how it goes but from the first attempt I always added vinegar and/or coffee depending the colour I want to get. It needs the acid to be able to soak in deeper in the paper’s tissue.
What was suprising to me was this mixture’s ability to keep the colours for a long time. Okay I don’t know for how long will they last but I’ve done these examples for more than a year ago and none of them were faded not even one bit.
When I finally ready with the mix I add water to it. This is also a factor when mixing the colours. I usually add only a few splash as it’s better to avoid diluting the mix. The water is hot, I wait a few minutes after boiling. I never tried boiling the vinegar and adding it straight to the mix though I should and I will at the next staining.
The hotter this mix is the earlier the effect takes on the paper but still needs a few minutes. My observation was that there’s no need to leave the paper in the mix for longer as it won’t do too much afterwards and if yes the paper will begin to molder especially at the sides, unless one want to achieve this effect.
Before I place the paper I mix the mix well avoiding the knots to be formed as it can ruin the smooth look though it can also have an interesting effect if that’s the goal.
If I find the right printer I then have to experiment with watercolour paper as it will react a different way in terms of how it soaks in this mixture and how it will react and keep the colour and so on.
I’ve checked the printers and papers you suggested and well worth to think about them, so thank you indeed! Also the hand colouring is something I might consider doing.
