Stock photography
Not all stock photos are equal. It’s not enough to simply search online and buy 4 or 5 photos that you like the look of. They’ll all be taken using different cameras in different light conditions. They won’t look like a coherent suite of photos. And you run the very real risk of infecting your brand with cliché – the same old photos everyone uses. This risk is higher due to the nature of search engines, giving everyone the same results for similar searches.
Anyone can buy a stock photo. But it takes experience to select a suite of appropriate, original and well matched images. This is a skill in itself, one best left to professional graphic designers.
