It’s often someone other than the writer of an article to choose a picture. Usually this is a stock photo that might not convey the intended message. Stock photos of older people are often patronising. They show young and old hands, or a young person looking lovingly at an older person. Most illustrations are far from inclusive.
Similarly, stock photos of wheelchair users often use non-disabled models and not real wheelchair users. An article and guideline from an illustrator discusses how to add diversity to your brand whether an organisation, service or a product. The title of the article is, Your Face Here: Creating illustration guidelines for a more inclusive visual identity.
“Words can set the tone for a company, but it’s the pictures that give it a face. Illustration has yet to find its place in the tech world, because it’s often unconsidered and thrown in on the fly. Whether being used to distill complex messages or add a touch of whimsy, illustration is one piece that makes up a company’s visual brand identity.” There are other interesting design articles on this blog site.
Also have a look at these stock photos of older people and see what you think. Note that they are all white and active – no diversity here.
