As a wedding photographer, I have a very specific set of fears that are beyond my control: that the vicar/registrar/celebrant has very specific rules for me, that the weather won't cooperate and it will be impossible to even get the cute umbrella shots and that the ceremony room will be SO. DARK. and tricky to subtly light whilst staying unobtrusive (see above vicar fears).  And the wedding industry is changing so much (in a good way!) in that weddings are now taking place year-round, not just in the super bright summer months, in unbeliavable locations and to stay relevant and current it's my job to continue expanding the tools in my toolbelt.
