Here’s an image from June 2015 – walking through Central Park in New York City.
As I processed this image, I first brought it into Photoshop CC 2015 and then used Topaz Simplify 4 to create a black and white simplified later – which smoothed the water and the foliage. Next I used a luminosity mask to have the simplified layer apply primarily to the darks in the image – having the lights and a bit of color punch through.
I like the effect – hope you do too!
