I was working with an older client putting together a pamphlet. They gave me zero input on design other than giving me a number of photos that were 100 kb or less that I begrudgingly put into a gallery wall. Otherwise, I gathered a number of free stock photos that vaguely suited their business. They matched thematically and looked good in the design.
Turns out, stock photos are catnip for boomers. Every revision I’ve made since (we’re now in round 4) has been moving these stock photos and replacing them with other sub-200 kb photos they discovered on an ancient hard drive.
