Rust is a Photoshop Action for Color developed for a vintage, classic, or timeless aesthetic. Rust creates hue shifts, especially in red and magenta tones, pushing them to a slightly desaturated greenish-brown. Rust also lifts shadows and reduces highlights, compressing the dynamic range to bring out detail in the image.  Rust works best with warm images, natural skin tones, and images with lots of red. *Although Rust is a versatile Photoshop action, it may not work best for images with lots of green.
