Fill layers let you fill a layer with a solid color, a gradient, or a pattern. Unlike adjustment layers, fill layers do not
affect the layers underneath them.

Adjustment layers provide the following advantages:
•
Nondestructive edits. You can try different settings and re-edit the adjustment layer at any time. You can also
reduce the effect of the adjustment by lowering the opacity of the adjustment layer.

•
Reduced loss of image data through combined multiple adjustments. Each time you adjust pixel values directly,
you lose some image data. You can use multiple adjustment layers and make small adjustments. Photoshop
combines all the adjustments before it applies them to the image.

Selective editing. Paint on the adjustment layer’s image mask to apply an adjustment to part of an image. Later you
can control which parts of the image are adjusted by re-editing the layer mask. You can vary the adjustment by
painting on the mask with different tones of gray.

same color and tone adjustments.
Adjustment layers increase the image’s file size, though no more than other layers. If you are working with many
layers, you may want to reduce file size by merging the adjustment layers into the pixel content layers. Adjustment
layers have many of the same characteristics as other layers. You can adjust their opacity and blending mode, and you
can group them to apply the adjustment to specific layers. You can turn their visibility on and off to apply their effect
or to preview the effect.

Keep in mind that an adjustment layer affects all the layers below it. This means that you can correct multiple layers
by making a single adjustment, rather than adjusting each layer separately.

Note: You can apply and edit adjustment layers only in Photoshop; however, you can view them in ImageReady.
Creating adjustment layers or fill layers
Adjustment layers and fill layers have the same opacity and blending mode options as image layers. You can
rearrange, delete, hide, and duplicate them just as you do image layers. By default, adjustment layers and fill layers
have layer masks, as indicated by the mask icon to the left of the layer thumbnail. If a path is active when you create
the adjustment or fill layer, a vector mask is created instead of a layer mask.

To confine the effects of an adjustment layer to a group of layers, create a clipping mask consisting of those layers.
You can place the adjustment layers in or at the base of the clipping mask. The resulting adjustment is confined to
