Research indicates that readers and viewers remember images long after words are forgotten. It is important that the national Church presents itself well in photographs. Amateur photos or photos of record such as members of a committee lined-up in a row are often good enough if the event is modest and the desired coverage is on social media. (However, even on this channel a professional photo is likely to attract more attention.)
An event may be of reasonable significance but there is no guarantee that the media will send a photographer not least because newspaper resources have diminished considerably in recent years. Organisations are increasingly commissioning their own photography of a high standard so that it may be considered for use in newspapers and on the Church and other websites.
A high-quality camera is like a paintbrush: The images it produces are only as good as the professional training and experience of the person who wields it. There are many with modest expertise offering low-cost photography – unfortunately with modest results. Even a technically competent photographer may produce disappointing results as their aptitude may primarily be for e.g. landscape photography. They may not have the experience, the speed or the confidence to persuade people to cooperate in a way which produces an eye-catching image for the press. It is for these reasons that for most newsworthy projects the Communications Department would recommend using an accredited professional photographer in the planning and budget.
