It’s not a secret. We all use stock imagery in our day-to-day design work. So why doesn’t anybody ever talk about it? Just like the inventory of a grocery store, not everything you see on a stock photo site is an ingredient for a gourmet production. By far the worst mistake you can make when choosing stock is selecting stereotypical or clichéd images to convey a concept.My guess is that we’re all just a little ashamed. We want people to see our work as just that: ours. When you have to tell someone that you didn’t create that grungy texture, or you didn’t take that beautiful photo, it feels a lot like admitting that you’ve cheated on a test. But this is nonsense—as designers, it’s our job to put things together and deliver a composition that looks good.
