I knew the importance of professional photos, but I didn't completely understand until I was asked for one and couldn't deliver immediately. If you are a business owner, blogger, writer - whatever your profession is - my best advice is to keep an updated, professional photo on hand.
Headshots are generally close-up photos of your head and shoulders. You are looking at the camera and should appear confident and approachable. Utilize these photos for business cards, corporate or business pages, branding, and professional websites such as LinkedIn.
Portraits are artistic and provide more range. Full-body photos, close-ups, and 3/4 lengths are great options for portrait photos. Similar to headshots, you can shoot portraits in a studio or on location. They, too, can be used for marketing, website photos, and social media sites.
No matter your profession, your photos should be fun, professional and should always express who you are. Enjoy!
