I had an Airbnb photographer take photos of my cottage/guesthouse and while she did a nice job visually, she took way too few. I had to supplement with some of my old photos to get more detail into the listing, and that just looks odd in the overall presentation. Is there a way to have her come back and fill in the gaps or have Airbnb send another photographer?
No. Just get a better camera or find a friend with a good SLR camera to take the pics you want.
Airbnb doesn't have staff photographers, the photographers you get through airbnb are doing it for very little money and more for practice and exposure. So don't bug the poor photographer.
