So you’ve been asked to take the photos at your friend’s wedding. You’ve tried to persuade them to hire a professional, but they are happy with you. Don’t panic, they asked you because they like your style. Wedding digital photography is no different from other photography, but there a few things you need to consider when planning for the big day.Turn off the sound on camera – there is nothing worse than the sound of electronic beeping during a solemn moment.Take more photos. A perfect moment will only happen once so don’t stint on the number of photos you take, this is one occasion when less is definitely not more. And don’t automatically discard shot you don’t think is good enough. Judicial cropping or editing may capture a moment you didn’t expect. The blurred shot of the flower girl – maybe there is an artistic photo here. Stand back and objectively (or perhaps subjectively) evaluate each shot for its own merits.Be prepared! Make sure you have spare batteries and multiple memory cards. Know the wedding venues and times. Check out places where you will be able to stand during the ceremony. Think about the shots the bride and groom will want of their big occasion and how you can move between them during the proceedings. The same applies to the reception venue. It is important to know where the speeches will be given and where the dancing will take place. When checking for locations for posed shots think about the background and places you can get good group shots of the entire wedding party.Be comfortable with the operation of your camera. A wedding is a busy event and at times a quite stressful one. There will be little opportunity to repose or reshoot if you hesitate with a shot. One option to reduce stress on you the photographer is to have an assistant. This could be someone nominated from the happy couple or someone you organise yourself. This person can spend time rustling people into groups, setting up shots and generally keeping things moving. This will leave you free to concentrate on the wonderful and flexible shots that come from wedding digital photography.Think about using the continuous shooting mode that your digital camera has. This will allow you to capture a second shot after the main shot has been taken. Sometimes you can just guarantee everyone will have their eyes open and be smiling one second after the shot is taken – don’t miss that opportunity.Weddings are a celebration. Make sure you cover off the tips above and your contribution to the day will be priceless.
