Photographer versus Dj...

We can not afford both. Both are the same price and 4 hour coverage. I am leaning more towards a photographer as they will give us the photos we will have the rest of our lives. Currently for music we just have Spotify playlists but the songs transition smoothly and don't drag on forever/no awkward silences (tooting my own horn here haha). We would just ask one of the venue staff or a good friend if they wouldn't mind just changing the dance songs (our first dance, mother/son etc) and then one the party music starts hitting play and letting it go. What do you guys think????
