DIFFERENT PHOTOSHOP SELECTION METHODS
To quickly select an object, try going to the Select menu and choose ‘Subject’. This command cleverly works out what the main subject in a photo is and creates a selection around it. It won’t work for every image, but often does surprisingly well. Here, it selected nearly the entire car in one step.
Magic Wand tool
Clicking with the Magic Wand tool creates a simple selection based around the sampled colour where you clicked. If not all the desired pixels are selected, you can use Select> Similar to select more pixels of a similar sample colour based on the same tolerance setting as the original Magic Wand selection.
Quick Selection tool
The Quick Selection tool offers a superior Magic Wand style selection method. Click, or click and drag once, to create an initial colour-based selection and keep clicking and dragging to add to the selection. Hold down the Alt key as you do so, to subtract from a quick selection.
