Sure I'll turn up to do the photography early, herd all the guests into the relevant groups, take all the pictured, deal with other guests who feel that jumping in front of the photographer because they want to take a snap on their phone, and then spend time after the wedding editing and processing the photos all using my expensive cameras and lenses plus my Adobe software I pay a subscription for. And I'll do this ALL for just a letter of recommendation and the possibility of tips (to be discussed later) I'm guessing that this is pending would be because they have a cousin who has taken snaps of the dog on their phone and they came out ok.
