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 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.
