Documentary wedding photography, candid wedding photography and wedding photojournalism are all essentially fancy names to describe the same thing. They are all about recording what actually happens during your wedding day. Something happens, then bam, we take a photo of it.
No, “Just move your arm up a little”, or “twist your head a little bit so the light is just perfect”. No, “let’s just pretend do your makeup again for the photo”. And absolutely no “Can you just pretend to laugh”. They may have advice on the best ways to do things, like the confetti shot or cutting the cake, but they won’t manufacture it in the moment.
