Final answer:
In the lab activity, the tool used to bend the neck of the swan is the Puppet Warp tool, which offers high control for precise image manipulation in Adobe Photoshop.
Step-by-step explanation:
In Tutorial 6 titled Master Manipulator in the lab, the tool used to bend the neck of the swan is the Puppet Warp tool. This tool allows for precise manipulation of specific parts of an image in Adobe Photoshop by placing pins for control points on a layer or within a selection and then bending or twisting the image around these pins. Unlike tools like Liquify or Smudge, which distort pixels more fluidly and continuously, the Puppet Warp provides a higher degree of control for transformations that require precise adjustments, such as bending a swan's neck with natural-looking results.
