There’s a school of thought which says anyone with a camera could take pictures. Why should pay high to hire someone to do it for you, if you can simply whip out your phone or fancy digital camera and snap away? With regards to wedding photography there’s even of school of thought who says you simply get all your visitors or guests to take pictures and upload them to a website for everyone to see. That is great, if you have some visitors who are skilled with a camera and are ready to spend your memorable event looking through the lens, rather than enjoying the occasion. In general, you’re much better off putting yourselves in the hands of an expert wedding photographer, in order that you end up with an amazing set of pictures which do justice your very special day.
