Hi,
I'm a portrait and event photographer and would love to shoot your headshots and speaking engagement. One of my specialities is shooting branding portraits for small business people, speakers and entrepreneurs. I love getting to know you and your audience, so together we can craft images that will get them interested in you at first glance.
As per your post, I propose to shoot headshots with you on arrival, followed by shooting your speaking engagement with a focus on: you speaking, you facilitating/working with the audience, you with whiteboard, participants (not recognisable), you looking at the camera as speaking (if possible).
Here are some examples of my work: [login to view URL]
I use a Fuji X-T1 camera with a 56mm f1.2 portrait lens for headshots. For events I use this camera and lens, as well as a 35mm lens and 16-55mm zoom lens. I will also bring with me a Canon 7D as a second camera.
I hope to speak to you soon, your event sounds fantastic and I would love to work with you,
Dan A'Vard
