When is it most advantageous to use a Healing Brush?

The Healing Brush tool is specifically designed for blending textures and fixing imperfections within an image. It functions by sampling pixels from the area surrounding the area you are painting, allowing it to match the texture, lighting, and shading of the original image seamlessly. This makes it an ideal choice for correcting blemishes, scratches, or other minor defects without leaving visible traces of the edit, thereby preserving the overall look and feel of the image.

In contrast, adding text to an image doesn't involve blending pixels or correcting imperfections, so options that pertain to text are not relevant here. Cropping is focused on adjusting the composition of an image rather than repairing it, thus using the Healing Brush during cropping would not be advantageous. Lastly, creating new image layers involves different tools and techniques that do not relate to the Healing Brush, which is meant strictly for retouching and enhancement tasks. Therefore, the use of the Healing Brush is optimal when aiming to blend in textures and fix imperfections, ensuring the edited areas are cohesive with the surrounding pixels.
