I think that they can take photos and will if you ask and they don't feel like as if it will interrupt their first priority which is focusing on you and the baby. You probably need to have a talk about them with it. And or look around for someone who you could invite as a silent observer who could photograph. Some photographers who are just starting out in birth photography, are willing to do it cheaper whilst they get some photos in their portfolio. Or just a friend you could trust in the space.... I def think that even if your mw's say that they want to concentrate when you are pushing baby out, they could either take some when you are labouring or remind your dh to take some. If I didn't have a photographer, I would write it down everywhere to remind my dh to do it.
