Whether you are an executive, a business owner, musician, actor, politician, celebrity, or all of the above; it's important to have a photograph that says something about you. The profile photo is the link to potential clients and your online presence. It says something about the image you would like to portray. It tells the public that you are reliable in your field. A good photographer will work with you to come up with a final photograph that captures what you envision this image to be.
Also important, is consistency on your website for businesses who have multiple employees. The profile photographs work better on the company website page if they are shot using the same photographer and their unique style. Hiring a sole photographer for this task is important for portraying a reliable and consistent business.
