Photographs and video are an enduring record of your wedding day, one you will both delight in and share with family and friends for years to come.
For the best results you need a skilled and empathetic professional who can capture those precious and fleeting moments. Although it may be tempting to cut costs this is one aspect of your wedding that shouldn't be skimped on.
Shortlist a number of photographers whose work you like. Most have web sites that you can browse before contacting them for a meeting. Another way of choosing a photographer is to pick a photography style you like and keep clippings from magazines of wedding photos you particularly like to discuss with your shortlisted photographers.
The way you relate to the photographer is just, if not more important, as their technical skill. You need to feel at ease and comfortable with them as people. Technical skill, artistic style and the photographer's ability to work unobtrusively are also things you should check out.
Similarly you should assess the videographer's previous work. Consider colour quality, clarity, audio levels, the flow from one scene to another and the overall story told about each wedding.
