Whether you hire a professional photographer or not, the important thing is to make sure the photo you use for LinkedIn is solid. Wear professional clothes and take the photo with good lighting against a simple background. Before uploading, crop the image so that your face takes up 60% of the photo. Do not use an over-filtered image, a selfie, or a low-quality, grainy photo. (Many colleges and universities bring in professional photographers to take LinkedIn headshots for their students so, if you’re still a student, check to see if this is an option.)
