Photographic print toning is like coloring a picture with special markers, but instead of using markers, we use chemicals to change the colors of a picture taken with a camera.
When we take a picture, we use chemicals and light to create an image on a piece of paper called a print. Normally, the picture is black and white or gray. But, if we add special chemicals to the paper, we can change the color of the print.
For example, if we add a chemical called sepia, the black and white picture will turn a brown color. This gives the picture an old-fashioned look, like it was taken a long time ago.
There are other chemicals, like selenium, that can make the picture have a blue, purple, or even red color. The chemicals change the colors of the picture by reacting with the silver in the paper.
Some people like to use toning to make their pictures look more artistic, and others use it to make the picture last longer by making it less likely to fade over time.
Overall, photographic print toning is a fun and creative way to change the colors of a picture and make it look unique.
