“Adjustment Layers + Masking”

1. Open a photo in Photoshop2. Use only ADJUSTMENT LAYERS3. Complete the following:

1. Edit the image BLACK AND WHITE2. Edit for CONTRAST, LEVELS, EXPOSURE, CURVES3. Hit “D” on your keyboard 4. Using the BRUSH TOOL, “erase” areas on the

ADJUSTMENT LAYER5. If you paint Black on the Layer Mask, it will mask

the effect of the adjustment in the Adjustment Layer. Likewise if you paint White on the Layer Mask it will cause the adjustment to take full effect. Grays in between will cause the adjustment to be only partially applied in that area.

Note: the BRUSH will only affect the AD LAYER, not the original image/Background

Adjustment layers create a “layer

mask” similar to quick mask
