To apply the Paint Brush artistic effect to a picture, what must you access?

To apply the Paint Brush artistic effect to a picture, you must access the Artistic Effects button in the Adjust group. This is because the Adjust group within the Format tab specifically provides tools for modifying the visual appearance of images, including applying various artistic effects that transform the way a picture looks. By selecting the Artistic Effects button, you can then choose from a range of styles that will apply the desired effect directly onto the selected image, effectively changing its texture and appearance to achieve the artistic look you want. This makes it the direct and designated method to access such image enhancements in PowerPoint. The other options do not provide the necessary tools for applying artistic effects directly to images.
