Before hiring a wedding photographer, take a look at their portfolio to understand their style and quality of work. Check out a variety of photos, such as posed shots, candid shots, and detail shots, to get a comprehensive view of the photographer's expertise. It's crucial to ask whether all the photos in their portfolio were taken by them or not, as some companies may have multiple photographers on staff, and you may be looking at images from photographers who are no longer with the company. This way, you can ensure that you view the photographer's work and accurately assess their skills and style.
