These two covers are so similar, I am guessing the photos were taken at the same shoot. The young woman on Boy Proof by Cecil Castellucci (Candlewick 2005) and the young woman on The Declaration by Gemma Malley (Bloomsbury 2007) look like the same person.
The paperback cover for Boy Proof has a more interesting type treatment, but uses the same photo (it seems to be clearer, but that may be the cover scan). The British cover for The Declaration is completely different and gives a different sense of what the book might contain.
I haven’t actually seen anything written about it, but I’ve noticed a huge increase over the last ten years in the numbers of book covers for children and teens using photography rather than illustration. With designers using stock photos more than ever before, it surprises me a little that we don’t see more book covers using the same photos or the photos from the same shoot. Do stock photo companies keep some kind of registry of who is using the photos that is available to designers? How much does price affect the choice to use photos over illustrations?
