“Adjustment Layers”The Problem With Photoshop’s Image AdjustmentsUnfortunately, as powerful as these image adjustments are,
they all suffer from one serious problem – they all cause permanent damage to our images. By that, I don’t mean you’ll get error messages telling you that your files are suddenly corrupt and won’t open. I mean that image adjustments make permanent changes to the pixels and level of detail in our photos.
Adjustment Layers Correct This:
1. Open a Photo in Photoshop2. Choose a NEW ADJUSTMENT LAYER3. Choose BLACK AND WHITE4. Edit using BLACK AND WHITE5. Choose a NEW ADJUSTMENT LAYER6. Choose LEVELS7. Edit using LEVELS8. Repeat Choose a NEW ADJUSTMENT LAYER
• Choose CURVES• Choose BRIGHTNESS AND CONTRAST• Choose CHANNEL MIXER• Choose GRADIENT MAP• Choose EXPOSURE
9. Experiment by turning ADJUSTMENT LAYERS ON/OFF using the
damage caused by using the IMAGE ADJUSTMENTS
commands
BEFORE AFTER
“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
