Indian wedding photography is a difficult topic to broach in such a way wherein you might find yourself struggling pulling something like this off especially if you are not all that familiar with the culture and with the practices that come along with it just yet. This does not mean that you should let this stop you from being able to get a professional job done though. You can always find your way around it for as long as you have every intent to do so.
Talk to the couple
Ask them if there is anything that you should make yourself aware of anything that you should observe during your coverage of the Indian wedding photography shoot. More often than not, they will give you anything and everything that you will have to work with at the end of the day and this is something that will get to pull you through one way or the other. Really take the time to sit down with the couple jus so that you will be able to really clearly map out what you are supposed to do and how you are supposed to manage yourself during the actual wedding celebration.
You should have a pretty good ratio of the planned shots against the candid shots. It should be a pretty good balance between the two. If you go for anything a little too far on either side of the spectrum and you end up with something that might be a little too much for the tastes of your clients. What you would want to do is to aim for a certain kind of balance between choreographed or posed shots and spontaneous shots. It will lend a more authentic vibe to the whole thing and something that can really make your photos come out as well put together as you would like them to be when it all comes down to it.
Get a wedding coordinator
You can almost always expect the couple and the bride in particular to be more or less a little more unavailable than you would like them to be during the wedding event. You might have some questions or things that you would need to sign off on in the middle of the Indian wedding photography shoot and they will not be there to cater to you and to your concerns. You should get a wedding coordinator ahead of time to help things move along a little smoother than usual for you. This person will serve as some sort of liaison between you and the clients. This person needs to be a key player in the wedding celebration, someone who will be able to make decisions for them in their absence. Get to know this person ahead of time and do your best to more or less establish some kind of a connection and a good working relationship with them at some point or so.
Know the sequence
You need to know what the sequence is and how the process of the entire thing will turn out. Talk to the facilitators of the wedding and figure out how things will pan out so that this is something that you can prepare for well ahead of time.
