There’s one more thing we’ll need to do to girl on rock.psd before we can place this image into the beach image. We only want to place the girl into the beach scene, and not the water surrounding her in her original image, so we’ll want to hide that in some way. We’ll do this in two parts: first, we’ll select the girl, then make the parts outside the selection transparent.
Using the Quick Selection tool to build a selection
You can use the Quick Selection tool to quickly click or drag to define a selection. The Quick Selection tool selects neighboring pixels that are similar to the ones that have been clicked. As you click or drag, the selection expands outward and automatically finds and follows defined edges in the image. We can adjust how precise the selection is by changing the brush size of the Quick Selection tool — a smaller brush size will make Photoshop focus on adding smaller areas to the selection at a time and will often result in a more precise selection.
Let’s start building our selection. We'll need to switch back to the file girl on rock.psd and select the Background layer before starting this process. Once we've done those things, we'll use the Quick Selection tool to build a rough selection around the girl.
For a walkthrough of how to select the girl, view the video Using the Quick Selection Tool. (do we want to put the actual video here, or just link to it? Thoughts, whoever’s editing this?)
