This is an image from earlier this year. I wanted to try it in duotone for the darkroom theme.
Now I want to explore this and similar techniques. It's lots of fun.
Some good info if you search duotone on digital photography school. Here's one article: https://digital-photography-school.com/2-methods-for-creating-duotones-in-photoshop/
Your title made me think of a dime store thriller... pulp fiction sort of thing. Thanks for the link to the info on creating duotones. I like the intensity of the colors and the long shadows in the shot... nicely executed. Can you give a link to the original photo?
