Wedding photography is actuallly mostly about salesmanship, and THEN actually making the images and up selling during fulfillment. Can you sell that add on to bride and brides’ mom?

A couple local wedding photographers/videographers  have an add on drone package (in case you want an aerial view I guess) - I can imagine that angle could be useful in video post, but I don’t know how often they sell that upgrade.   A 360 view sort of seems like the same sorta thing…all the traffic will bear, etc. 

So far as an add on,  a photo booth service has been the most successful and popular add on to a basic package for me.

This!   Offer it in your packages.  IF there is indeed a "niche" market for it, then it will take off.
