Callum Harrison created a magazine called "Vocal Success" for a school project. He experimented with different images, logos, and designs to create a professional-looking magazine cover in Photoshop. Some of the techniques he used included adding light effects in the corners, separating text with lines, removing backgrounds, adjusting saturation levels, and choosing fonts. In the end, he produced a finished magazine cover design for "Vocal Success" that looked like it could be a real music magazine.
