Some days, the light just doesn't cooperate to give you that beautiful blue sky in the background of an image. But your subject may be so compelling, you know you have to fix that sky to make elevate your image from mundane to impressive. You could always replace the sky in Photoshop, but there may just be an even easier way to do it using the Black and White Filter.
How will the Black and White Filter make your colors pop? Colin Smith from photoshopCAFE explains in this one-minute video that a black and white layer in luminosity mode will give you incredible control over the colors in your image.
Simply adjusting the color sliders (red, green, blue, cyan, yellow, and magenta) allows you to deepen the blue sky, or set off the red in an image.
In addition to subtle tweaks that make your colors pop just a bit, you can also get creative and completely change the look of your image by making drastic changes to the sliders. And since it takes less than a minute to make the changes, you can tweak many images quickly, making it an invaluable addition to your workflow.
