When doing wedding photography, I find it's really helpful if you're using two cameras. Source one that you can use – either by borrowing or getting an extra one that you've got – and fit it with lenses which are different from the initial one. For example- Wedding Photographers in Wiltshire uses two cameras in wedding photography. Get a wide angle lens and set it on one camera. This is perfect if you're taking candid pictures or shooting in tight areas. The other camera should have a longer lens; go as high as 200mm if possible.
Remember that when doing wedding photography, you need to be bold with taking the pictures but you shouldn't be an obstruction. You must be bold at taking a particular shot that you think is lovely.
At precisely the same time you must attempt to never disrupt what is going on. Remember that this is a special day for the couple and you are just there to capture the memories. You get the chance to request all the presents you want once you're already taking the formal shots.
Think about the placings and the poses that you believe will make the picture work. Diffused light can be your very best friend when you are doing wedding photography. You have to have the ability to bounce the flash.
