Affinity Photo lets you make duplicate layers to increase workflow or to temporarily create a 'backup' layer. A power duplicate feature also allows you to duplicate and repeatedly transform layer contents.
Do one of the following:
On the Layers panel, -click a layer or group and select Duplicate.
On the page, drag a selected layer with the pressed. While dragging, release the key to move the layer instead, or press the key while moving to duplicate rather than move.
If you duplicate a layer(s) and then transform the duplicated contents, you can immediately duplicate the layer containing the transformed content. The transform is applied accumulatively to subsequent duplicates.
To power duplicate:
Select the layer(s).
From the Layer menu, select Duplicate.
Transform the duplicated layer content.
From the Layer menu, select Duplicate. A duplicate is created and the transform is automatically applied to the duplicate.
Repeat step 4 to create more duplicates with the transform accumulatively applied.
If you have made a selection, you can immediately duplicate the selected content into a new layer (or layers).
To duplicate selected content:
Select content within the layer(s).
From the Layer menu, select Duplicate Selection.
The selected content will be duplicated into a new layer. If content has been selected across multiple layers, the content will be duplicated into multiple separate new layers.
