The banner is designed by using Adobe Photoshop.
First, the background is filled with Radial Gradient. Then, texts are inserted onto the background.
After that, two pictures that found online are inserted onto the background.
Then, the third picture that found from the Internet is inserted onto the background. And finally, texts “Reduce, Reuse, Recycle” are inserted into the light bulb.
The banner design is intentionally designed as a “Z” shape. This is because the purpose of the banner is to lead the audiences read from the top left to bottom left, then to the main point of the banner, which is located at the bottom right.
