If you are troubled by blemishes big or small in your portrait work, this 16-minute tutorial by Nathaniel Dodson over at Tutvid will teach you how to use Photoshop to properly clean and heal skin in a flash.
Dodson shows you how to eliminate acne, pimples, and other blemishes using 5 different tools: the Camera RAW filter, the Spot Healing Brush, the Healing Brush, the Patch Tool, and Frequency Separation. Each of these tools offer their own advantages, and by using a mix of all 5, you can remove marks and blemishes quickly and without much fuss.
You will learn: How to use a non-destructive workflow—always a good practice in case you remove one mark too many, or want to go back and alter your work; the difference between the spot healing brush and the healing brush, Dodson’s favorite tool for removing skin blemishes; and, finally, he even throws in a bonus technique that will help you tone down wrinkles when photographing elderly subjects.
