Adjustment Layers



336-280


Adjustment layers apply color and tonal adjustments to your image without permanently changing any pixels on the original photograph.

The color and tone adjustments are stored in the adjustment layer and apply to all the layers below it.

Rather than making a Levels or Curves adjustment directly on your original image, you can easily achieve the same results on  a layer.


Adjustment Layer Advantages


Here are some compelling reasons for using Adjustment Layers:

  1. Non destructive editing.  You can try out different settings and even go back after they are applied and change them without affecting the original document.  The opacity of the layer can also be changed to lower the effect of an adjustment.

  2. Reduced loss of image integrity through multiple adjustments.  Each time an adjustment is applied to an image there is a slight bit of data loss.  Adjustment layers make the adjustment without affecting the original image.

  3. Masking Ability.  After making an overall adjustment it can be removed from part of the image using masks.

  4. Copy and Paste Adjustments.  Adjustment layers can be copied and pasted between different documents to apply the same adjustment to multiple images.

  5. Really unique Blending.  The way one layer blends with a layer below it can be modified and changed in unique, effective and surprising ways.

From my experience (granted it is not the Photoshop Guru level) the most useful and most often used adjujstment layers and their inclusion in the three software packages are as follows:

Levels Yes Yes Yes
Curves Yes No Yes
Channel Mixer Yes No Yes
Hue Saturation Yes Yes Yes
Photo Filter Yes Yes No
Invert Yes Yes Yes
Brightness/Contrast Yes Yes Yes

It is easy to see, then, that Photoshop (full version) has the largest number of useful adjustment layers followed by Paint Shop Pro and then Photoshop Elements.

In practise Photoshop is the most versatile of the three programs followed closely by Paint Shop Pro with Photoshop Elements being the least versatile.

Blending Modes

Not only are adjustment layers really, really useful and powerful on their own but there is also the consideration of how they Blend with the layers below them.

Both basic and advanced blending is included with both Photoshop and Paint Shop Pro and only the basic blending is included with Photoshop Elements.
