The Object Selection tool simplifies the process selecting a single object or part of an object in an image—people, cars, furniture, pets, clothes, and more. You simply draw a rectangular region or a lasso around the object, the Object Selection tool automatically selects the object inside the defined region. The tool works better on well-defined objects than on regions without contrast.

You can access the Object Selection tool at the following locations:
- From the main application Tools panel in Photoshop.
- From the Tools panel in the Select And Mask workspace.
Choose a selection mode and define a region around the object.
In the options bar, choose a selection Mode: Rectangle or Lasso.
In the options bar, click one of the selection options: New, Add To, Subtract From, or Intersect With the selection.
New is the default option if nothing is selected. After making the initial selection, the option changes automatically to Add To.
Add to the selection
Hold the Shift key or select Add To Selection in the options bar, then draw a new rectangle or a lasso around the missing region. Repeat this process for all the missing regions you want to add to the selection.
Subtract from the selection
There are two options to subtract from the selection:
1. Use the Subtract From Selection option in the options bar
- Turn OFF the Object Subtract option in the options bar.
- Hold the Option (Mac)/ Alt (Win) key or select Subtract From Selection in the options bar, then draw an exact rectangle or a lasso around the boundary of the region you want to subtract from the selection.
2. Use the Object Subtract option in the options bar
Object Subtract is especially useful when removing the background regions inside the current object selection. You can think of Object Subtract option as equivalent to Object Selection inverted. So, you can draw a rough lasso or a rectangle around the region to be subtracted. Including more of the background within the lasso or the rectangle region produces better subtraction results.
- Turn ON the Object Subtract option in the options bar.
- Hold the Option (Mac)/ Alt (Win) key or select Subtract From Selection in the options bar, then draw a rough rectangle or a lasso around the region you want to subtract from the selection.
(Optional) Choose object selection options
Sample All Layers: Creates a selection based on all layers instead of just the currently selected layer.
Auto-Enhance: Reduces roughness and blockiness in the selection boundary. Automatically flows the selection further toward image edges and applies some of the edge refinement you can apply manually in the Select And Mask workspace.
(Optional) Further refine the selection edge in the Select And Mask workspace
To further adjust the selection boundary or view the selection against different backgrounds or as a mask, click Select And Mask in the options bar.
The Select Subject command lets you select the most prominent subject in an image in a single click. Powered by advanced machine learning technology, Select Subject is trained to identify a variety of objects in an image—people, animals, vehicles, toys, and more.
Access Select Subject in one of the following ways in Photoshop:
- While editing an image, choose Select > Subject.
- While using the Object Selection tool, click Select Subject in the options bar.
- While using the Quick Selection or Magic Wand tools, click Select Subject in the options bar.
- While using the Quick Selection tool in the Select & Mask workspace, click Select Subject in the options bar.
Select Subject automatically selects the prominent subjects in the image. You can then refine the selection using other selection tools. For example, in the illustration above, use the Subtract From Selection option with another selection tool to remove the part of the sidewalk included in the automatic selection.
For more information on refining selections, see Adjust pixel selections.
A. New selection B. Add to selection C. Subtract from selection D. Intersect with selection
You can use the Quick Selection tool to quickly “paint” a selection using an adjustable round brush tip. As you drag, the selection expands outward and automatically finds and follows defined edges in the image.
To change the brush tip size, click the Brush pop-up menu in the options bar, and type in a pixel size or drag the slider. Use the Size pop‑up menu options to make the brush tip size sensitive to pen pressure or a stylus wheel.
When creating a selection, press the right bracket (]) to increase the Quick Selection tool brush tip size; press the left bracket ([) to decrease the brush tip size.
Sample All Layers
Creates a selection based on all layers instead of just the currently selected layer.
The selection grows as you paint. If updating is slow, continue to drag to allow time to complete work on the selection. As you paint near the edges of a shape, the selection area extends to follow the contours of the shape edge.
If you stop dragging and then click or drag in a nearby area, the selection will grow to include the new area.
- To subtract from a selection, click the Subtract From option in the options bar, then drag over the existing selection.
- To temporarily switch between add and subtract modes, hold down the Alt (Windows) or Option (Mac OS) key.
The Magic Wand tool lets you select a consistently colored area (for example, a red flower) without having to trace its outline. You specify the selected color range, or tolerance, relative to the original color you click.
You cannot use the Magic Wand tool on an image in Bitmap mode or on 32‑bits-per-channel images.
Determines the color range of selected pixels. Enter a value in pixels, ranging from 0 to 255. A low value selects the few colors very similar to the pixel you click. A higher value selects a broader range of colors.
Selects only adjacent areas using the same colors. Otherwise, all pixels in the entire image using the same colors are selected.
