Zion Moon, Processed as a Tritone

Zion, converted to B/W Tritone Image

Still in pursuit of black and white imagery I processed yesterday's image as a tritone in Photoshop CS6.....Fairly simple to do:

1. GO into adjustments and choose gradient map
2. GO image and convert to gray-scale and flatten
3. You should now be able to go into Image and choose Duotone and the dialog will look like this: be sure to convert to  an 8 bit image.


4. Then you can use the Type dropdown and the custom to create duotone, tritone and quadtone images by mixing and matching to suit your taste.
5. Once finished convert back to 16 bit RGB for printing. 

Give it a shot....
