This deserves its own section, because it is the most underused add on in corporate event work and the one attendees remember.
The setup is small: a backdrop or a chosen wall, two lights, a chair or a taped mark on the floor, and a laptop. It runs for a defined window, usually across the two longest breaks or the first ninety minutes of registration, in the prefunction area or an unused breakout room. An attendee walks up, sits or stands for around ninety seconds, sees the frame on a screen, and moves on.
Why event teams book it. Most professionals have a headshot they dislike, taken at least four years ago, cropped out of something else. Offering a free professional one is a genuine attendee benefit that costs the organiser a corner of a room. Queues form voluntarily. People post the result themselves, tagged, which is the only organic event promotion that reliably happens after the fact.
Why sponsors fund it. A headshot station is a booth people actively want to visit. Branding on the backdrop wall, a sponsor logo on the delivery email and a sponsor representative handing out cards next to the queue is a far better activation than a table with a bowl of pens. If a sponsor is looking for something to underwrite, this is the easiest sell on the sheet.
What it requires. Roughly a ten by twelve foot footprint with a wall behind it, one standard power circuit, and a second person to manage the queue and capture names so the images can be matched to people afterwards. That second person is not optional at any real volume. Without them, you finish the day with four hundred unidentified portraits.
Delivery. Individual images delivered by email or a searchable gallery within a few days, consistently retouched to the same standard, cropped to both square and vertical so they work on every platform an employee will use them on. Consistency is the whole point: an executive team with fourteen headshots from fourteen different sources looks like fourteen different companies.
