They can, but that's not what they actually mean here.
In this case, it would be more accurate to say that the energy of the photon is being used to excite an already existing electron.
As for creating electrons from photons: if you collide two photons at the correct energy level, you can get an electron-positron pair. This is a very high-energy process, and not how cameras work.
