Photographs, if taken well, are a fantastic way to remember elements of the day and of course, the formal photographs after the ceremony are a must, but only video can capture every detail of the day - including many moments that are missed in the rush of the day.
So much happens in such a short space of time that it's very hard to take it all in and remember everything, especially with the high emotions of the day and of course, many parts of the day (for example, the guests arriving) will not have been seen by the Bride or the Groom. Another huge plus is that you will be able to share a DVD of the day with family or friends who are not able to attend for one reason or another.
On a personal note, my wife and I really treasure our wedding DVD because it has precious footage of my grandparents (who have since passed away), not only attending the wedding but leaving us a personal message to camera as well. This is something we have especially valued as it helps us not only remember them, but we can now also show our children who did not get to meet them.
You could let "Uncle Joe" film the day but couples are often be left with shaky, out of focus footage of the back of guests' heads along with muffled audio - resulting in the video not being watched again.
A wedding film should cover much of your day, from the guests arriving at the venue through to the first dance of the newly married couple. You will be able to choose exactly how much of this is included in the final film - you may decide that you'd like the wedding ceremony condensed and only key parts included. Other parts of the day, or the days leading up to the big day, can also be included in your final film. This could be the stag and hen parties or the bridal preparations on the morning of the wedding.
In the right hands, a wedding film will bring back to life the emotion of the day through beautifully shot images and life-like sound reproduction. A professional wedding videographer will also make sure that he or she is completely discreet and unobtrusive. Their role, unlike a photographer who will "stage" formal shots, will be to stand back and capture all the natural moments of the day. The final result will be a wonderful DVD that can be watched again and again on wedding anniversaries throughout your life.
