I know why you're here. Because nowadays your online image is your brand.
It is important.
You want to show people that you know what you're doing (CONFIDENT) and that you're great being around while you're doing it (FRIENDLY).
You also want to showcase your own charisma, your own signature, whatever you're quiet, emphatic, or meaning business, leave the BEST FIRST IMPRESSION and be MEMORABLE.
I shoot either in studio or location, either for INDIVIDUAL session, or CORPORATE session (several head-shots, executives, environmentals, groups...).
Everybody needs a great Headshot.
