Good architectural photography is critical for a lot of businesses. There are many advantages to showcasing the architecture of where you work or what you have built (if you are in construction for example). You may be showcasing your products (in the case of construction businesses), what you are selling (if you are a developer or real-estate agent) or showing your business premises creates a sense of professionalism and trust for your clients. It can legitimise your business and creates awareness of where you are and makes it easier for clients to find you as they know what they are looking out for.
Professional Architectural Photography takes great skill and technique. It requires not only a great many other photography cross over skills (use of light, composition, camera usage basics such as shutter and aperture) but also more detailed knowledge of lens distortion factors.
