To edit an adjustment or fill layer
You can edit an adjustment or fill layer’s settings, or replace it with a different adjustment or fill type.
You can also edit the mask of an adjustment layer or fill layer to control the effect that the layer has on the image. By
defa
ult, all areas of an adjustment or fill layer are “unmasked” and are therefore visible. (See “Masking layers” on
page 432.)
1 Do one of the following:
• Double-click the adjustment or fill layer’s thumbnail in the Layers palette.
• Choose Layer > Layer Content Options.
2 Make the desired adjustments, and click OK.
Note: I
nverted adjustment layers do not have editable settings.
To change the type of adjustment or fill layer
1 Select the adjustment layer or fill layer that you want to change.
2 Choose Layer > Change Layer Content and select a different fill or adjustment layer from the list.
Merging adjustment layers or fill layers
You can merge an adjustment or fill layer several ways: with the layer below it, with the layers in its own grouped
layer, with thelayersitislinkedto, andwithall othervisiblelayers. Youcannot, however, useanadjustmentlayer or
fill layer as the target layer for a merge. When you merge an adjustment layer or fill layer with the layer below it, the
adjustments are rasterized and become permanently applied within the merged layer. You can also rasterize a fill
layer without merging it. (See “To rasterize layers” on page 407.)
Adjustment layers and fill layers whose masks contain only white values do not add significantly to the file size, so it
is no
t necessary to merge these adjustment layers to conserve file space.
