This is a photo of Rapid Creek in Darwin and then converted to sepia tones.
I did this with a few clicks of the mouse.
In the 'olden days' it was a bit more complex.
It was actually quite dark in here at the time I shot this. This is a 13 second exposure with a bit of light painting of the foreground with a L.E.D torch.
Sepia Toning. The word “sepia” comes from the taxonomy of a Cephalopod, a group of creatures that include the Cuttlefish! Now, any guesses as to why a fish’ name would be used to signify the tone of a photographic image? Maybe you’ve already guessed! Originally, the process of sepia toning an image involved adding a pigment made from the inky secretions of a cuttlefish during print development. Later, artificially developed toners replaced this purely organic (and underwater) pigment.
In sepia toning, chemicals are used to convert the metallic silver in the print to a sulfide compound called silver sulfide (Ag2S), which is 50% more stable than silver, making it more resistant to environmental pollutants. Therefore, people in the olden days originally processed/developed their images in sepia to make them last longer.
I guess our forefathers were smarter and more perceptive than we are today, or perhaps they just cared about ensuring that things were made to last!
