Different photographers will have different approaches to projects. Events photography can be as cheesy or natural as the photographer want it to be, and the photojournalist approach is all about reporting on the day’s events.
This means that there are no cheesy photos where the guests are forced into different positions. It’s a kind of ‘fly on the wall ‘approach and it means taking a step back, out of peoples way and photography them as they engage with each other.
If you like a great deal of control over your photos than this probably is not the style for you, and you do have to have strict rules if you really want to take on the photojournalist approach. There will always be natural smiles, natural movements and plenty of opportunities for cracking photos, but you have to be patient with this approach, and it takes time to perfect.
