Welcome to my second tutorial on removing the background from your images in Photoshop. This tutorial covers using Levels and Channels, along with Masks. These tools are quite effective in preserving the hair when removing the background from your images. Keep in mind that the sequence mentioned in the tutorial works very well for the image provided, you may need to make some adjustments depending on the complexity of your own image.
It might be easier if you use the same image I did and follow along the first time so you can download that same image below.
