Ever seen photos with just a little splash of color while the rest of it is in grayscale? It’s a neat little trick photo-editors use to make certain elements of the image ‘pop’. I have tried using it successfully for quite some time now but the results still never fail to mesmerize me. All you do is use the ‘Select tool’ to make a clean selection of the region you want to keep, ‘Inverse’ your selection to select the area that needs to be converted to gray, and using a ‘Desaturation Mask’, bring the saturation levels all the way down. Here is a little example to show my point. Do give this a try and let me know how yours turned out!
