ON1 Photo RAW wields some incredible possibilities for Black and White processing. In this tutorial, I will show you how I use the Effects Module in ON1 Photo RAW to make incredible Black and White images.
The key here is to put a Black and White Filter above a Color Enhancer Filter and use the color data to enrich the Black and White Tones. By increasing the intensity of the Blue information in the photo I was able to make dramatically darker skies in my Yosemite images.
