Network accordingly with your peers.
Wedding videography is basically a challenging and interesting business to get into. You will need a lot of work as well as a lot of resourcefulness if this is anything that you would like to thrive in one way or the other. While you are covering the wedding event, have your second shooter go around and ask the rest of the vendors such as the florists, wedding planners, caterers, and so on and so forth. Ask for the business cards of everyone there and collate their contact info.
Ideally, as your experience grows and as you go ahead and cover more and more weddings, your contacts list will basically grow even more. You should have a scrapbook or a sort of catalogue wherein you can categorize your contacts list based on the kind of service that they provide. More than that, you will have all of your information intact for when you are writing down your vendors list at the bottom of your blog once you cover the wedding. You will also be able to bring in a lot of business through referrals.
Be agile and only carry gear that you absolutely need.
Be on your move all of the time. Walk around a lot and try out a lot of different angles and perspectives as much as you possibly can so that you will be able to get the most interesting points of view and angles as well. Prepare all of the gear that you need but make sure that you technically only bring those that you need. If you over pack, you will be lugging around too much gear and that may not be too friendly for your back. Bring only the absolute requirements such as your camera, your second camera, your tripod, your various lenses, memory cards and extra camera batteries, and a high quality camera bag that will bring all of your gear tomorrow.
Always have backups for your audio.
Audio is extremely important for your wedding videography craft. Bring along some spare external audio recorders so that you are able to guarantee getting an audio in the best possible audio ever. If the bride and the groom have hired a DJ, try to get in touch with that DJ and ask if you can use his equipment for your backup audio.
Traditional wedding shots are must-haves.
Even the new and trendier couples out there who would like to have an alternative perspective for their wedding videography approach would still want to have their traditional wedding moments captured intact. Make sure that you do not forget about any of those. As a matter of fact, you would need to have a list of all of the important shots that you would have to take and keep that said list with you as much as you possibly can.
Camera stabilization is crucial.
You need to bring in a tripod, period. Panning and stabilization is so much easier for when you are shooting the wedding video newcastle.
