Natural light is limited in winter, which means scheduling your wedding – or at least your photos – in the few hours of daylight available. Aim to have your ceremony sometime between 11am and 1pm to make the most of the light. 2pm may be possible in the south of the UK if you are having your wedding and reception at the same venue. If timings allow, I always try to get my couples outside for a few shots at sunset, too.
Make sure you hire a photographer who is comfortable and experienced with using a variety of lighting techniques, including off-camera flash. The techniques and equipment required to take amazing photos when natural light is lacking, such as during winter weddings and in dim wedding venues, are very different to those needed for shooting outdoors on a bright spring or summer day.
