Using adjustment layers

Use adjustment layers to apply an adjustment to your vector/pixel layer (or object). This is carried out non-destructively (i.e., without permanently affecting the original layer or object).

About adjustment layers

Adjustments are applied from the Layers panel and most include customisable settings alongside general adjustment options. Once applied, they can be identified as both an adjustment and a specific adjustment type by using unique symbols.

Adjustments can be symbolised, i.e. their settings can be updated across multiple instances of the adjustment layer at the same time.

Available adjustments:

When an item is selected, the adjustment layer is applied to just that item, i.e. it is clipped. With no selection in place, the adjustment is applied to the entire spread.

Adjustment layers also have mask layer properties. Areas of an adjustment layer can be revealed or hidden in the same way as with a mask layer.

Adjustments To apply an adjustment:
  1. On the Layers panel, do one of the following:
    • Select a layer to add the adjustment as a child of the layer. It will affect all objects on the selected layer.
    • Select an object, group or image to add the adjustment to the item, affecting just that item only.
    • Deselect all items to add the adjustment at the top of the layer stack, applying the adjustment to all items below it (the entire spread).
  2. Click Adjustments and select an adjustment from the pop-up menu.
