Make selections in your composites

Select the Object Selection tool.

Hover over the image to automatically select the desired object or region. The Object Finder is enabled by default and ensures you see a spinning refresh icon. 

Uncheck this option if you'd prefer to use the Rectangle or Lasso selection mode and drag to make your selection.

• Rectangle: Drag the pointer to define a rectangular region around the object or region.
• Lasso: Draw a rough lasso outside the object's boundary or region.

Select from these options:

• New selection: This is the default option if nothing is selected. After making the initial selection, the option changes automatically to Add to selection.
• Add to selection: Select this option from the options bar, then hover over or 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 selection: Select this option from the options bar, then hover over or draw a rectangle or lasso around the boundary of the region you want to subtract from the selection. It's particularly useful when removing the background regions inside the current object selection.  
• Intersect with selection: Select this option if you want to keep only the areas where two or more selections overlap. 

Use these options to let Photoshop analyze all visible layers and help make clean selections. 

• Sample All Layers: Creates a selection based on all layers instead of just the currently selected layer.
• Hard Edge: Enables hard edges on the selection boundary.
  

Select Select And Mask from the options bar to further adjust the selection boundary or view the selection as a mask.

Select Select Subject from the options bar. 

Select Add to selection and Subtract from selection to refine the initial selection.

Use the tools in Select and Mask to further refine your selection. 

Select the Quick Selection tool. 

To refine your selection, select New selection, Add to selection, or Subtract from selection from the options bar.

Select the brush pop-up menu in the options bar if you wish to change the brush tip size and enter the pixel size or drag the slider.

Select the Size drop-down menu to turn off brush tip sensitivity or make it sensitive to pen pressure or stylus wheel.

Check these options:

• Sample All Layers: Creates a selection based on all layers instead of just the currently selected layer.
• Enhance Edge: Automatically improves the edges by making them smoother and more refined.

Paint over the area you want to select and the tool expands the selection as you go, automatically following the edges of shapes in the image for a more precise selection.

Select Select and Mask to adjust the selection boundary further. 

Select the Magic Wand tool.

Select from Add to selection, Subtract from selection, or Intersect with selection from the options bar. The tool's pointer changes depending on the option selected.

Make selections for:

• Sample size: Controls how much the image is sampled and affects the sensitivity of the tool when selecting pixels of similar color.
• Tolerance: Determines the color range of selected pixels. Enter a value in pixels, ranging from 0 to 255. A low value selects fewer colors and a higher value selects a broader range of colors.
• Anti-alias: Creates a smoother-edged selection.
• Contiguous: Selects only adjacent areas using the same colors. Otherwise, all pixels in the entire image using the same colors are selected.
• Sample All Layers: Selects colors using data from all the visible layers. Otherwise, only colors from the active layer are selected.

Select the color in your image. If you select Contiguous, all adjacent pixels within the tolerance range are selected. Otherwise, all pixels in the tolerance range are selected.
