Every design in Photoroom is made up of layers, so it is important that you understand what layers are and how they work.
Here, we explain the:
Basic concept of layers
Benefits of layers
Difference between a background layer and an "object" layer
Stack order and its effect on your final design
Use of layers in AI-generated images.
For instructions on how to work with layers, see the various layer articles.
What are layers?
When you import a photo into Photoroom, it converts it into a design. The design consists of two or more layers:
Background layer
One or more foreground layers, which are also known as "object layers".
In the image below, the bar of soap is on the "Product" layer and the background of the image is on the "Background" layer. Each layer contains a different part of the overall design and they are stacked, so that the "Background" appears behind the "Product" layer.
Why are images separated into layers?
Having the different parts of an image on different layers gives you more control. Each layer has its own settings so that you can apply stylish effects that apply only to that layer, such as shadows, colors, and reflections.
In the following image, a Mono filter has been applied to the background layer to make it appear in black and white. The object layer has had its colors altered so that they are in red and purple tones. Notice how the Mono filter does not affect the product layer and, similarly, the change in color on the product layer has no effect on the background layer.
Layers also give you more control over the positioning of objects in your image. You can move layers to different positions and place them behind or in front of other layers.
What are object layers?
Object layers are the foreground layers that Photoroom creates for you, when it imports a design. We call them object layers as they typically contain objects, such as products, people, or logos.
Note: Object layers have to be placed in the foreground, in front of the background layer.
Using the bar of soap design again, you can see that the soap part of the image is on the object layer named "Product". It is above the "Background" layer in the Layers list, which means it is in the foreground. The layers are listed in a stack order, which we will explain later in this article.
Note: Photoroom names the object layers automatically and you cannot rename them.
How to view the layers in a design
When you open a design in the Photoroom editor on mobile devices, select the Layers button to display a list of the layers.
On the Web App, select the background of the editor to display the layers list in the side panel.
Is the order of the layers important?
Yes. There is a stack order to the layers.
The background layer is on the bottom of the list. This represents the background of your design and is the "deepest" layer.
Each object layer is placed in front of the background layer, and has to be on its own level. You can change the order of the object layers to move layers behind other layers or in front of them.
How to edit a layer
When you select a layer in the editor, the layer's settings appear. Each layer has its own settings and that's where you can apply changes that only affect that layer. There are a wide range of changes you can make to a layer, from changing colors and applying shadow effects to inserting new layers.
Note: On the Web App, some layer settings are also available from a context menu which appears when you right-click on a layer.
Do AI Images use layers?
Yes, but not in exactly the same way as non-AI designs.
When you use Photoroom to generate an AI Image, the resulting AI Image is always on a single layer. For example, if you use AI to create a photo of a ring on a silk sheet, the silk sheet and the ring are on the same layer. The AI Image does have a background layer, but it is empty.
The same idea applies when you add an AI Image to an existing design. Photoroom will generate the AI Image on a single layer. That layer is added to your existing design. You can add extra layers on top or behind the AI Image layer, just like you could on a non-AI design.
