Adjustment layers are the cornerstone of non-destructive editing in Photoshop.
Adjustment layers are the cornerstone of non-destructive editing in Photoshop. By using them, we can apply color and tonal adjustments to our image without permanently altering the original layer. These include but are not limited to Brightness/Contrast, Hue/ Saturation, and Color Balance adjustments. For instance, to modify the mood of our image, we can adjust the Hue/Saturation layer to fine-tune colors or change them completely.
