The Digital Photography 101 infographic from The Backdrop Store is a great primer for newcomers to the basics of photography.
This is a great use of an infographic as a high level summary that invites people to your website and to their much more detailed Digital Photography 101: The Definitive Guide for 2018
I usually advise against full color photos in infographics because they are visually noisy, and multiple photographs add multiple color palettes to one infographic design. However, in this case the topic is specifically about photography, so the use of photos is very relevant and appropriate. Notice the simple color scheme of the rest of the infographic so the photos can stand out and don’t compete against the basic design.
