1. Create a must-have shot list and keep it on you all throughout the coverage of the wedding event.
This is something that has been happening between wedding photographers and brides and it is something that is basically as old as time. Brides usually get disappointed with wedding photographers who neglect or miss out on some of the most important moments that they would like to get documented in their wedding. This is one of the most common things that brides and photographers disagree about at some point and something that you might want to take care of and get out of the way as much as possible and as early on as you can. The best way for you to be able to go about with an embarrassing and dissatisfying situation such as this would be to have a long and good talk with the bride.
Discuss all of the important moments that the bride thinks she absolutely cannot do without.
Make sure that this is something that you are able to get down on an actual and physical paper list. You should then proceed to go ahead and see if there are any items that you would like to add on for good measure. Having a must-have list would mean that you will be able to keep track of things that you have already captured. Cross things out as you along the way and keep the list on you until you are done with the coverage. Over time, this is something that you basically get better with and you will not need the list at all once you have them all committed to memory.
Change your camera lenses every now and then.
There are some instances wherein people in the wedding tend to get a bit awkward and a tad bit too uncomfortable when you are up in their faces all the time. Sometimes, you need to scoot back a little and get out of the way and pretty much take your photos from a comfortable enough distance. You need to make sure that you are able to arm yourself with all of the right equipment that you will need. You need a telephoto lens that will let you take all of the right photos from a distance. That is usually the main reason why you need at least two cameras so that you can house or mount two different lenses on them. It is way faster and way easier for you to swap in between cameras than to have to keep fumbling with different kinds of lenses at some point. Actually, this is a great way to start when filming the couple. Start from a comfortable and far enough distance then work your way forward as you go along.
Know the people around
It also helps if you go through the trouble of finding out the names not just of the bride and the groom but of the people who are close to them as well. Try to figure out who the maid of honor and who the best man is as well. Try to be on first name basis with them if you can pull it off.
