While working at K2 (2007-2011) I designed a lot of corporate marketing:
Event Booth artwork, email campaigns, micro-sites, architecture diagrams, animations, branded clothing, case study brochures, outdoor branding, corporate documents, business cards, splash screens, print adverts in magazines, and Sales Decks / PowerPoint presentations for the various conferences around the globe.
Below is a small sample of the work made for the Microsoft Tech-ed Africa 2010 event
In some cases where the event organisers had a 3D CAD model of the event booth — I would ask for it. Convert the 3D AutoCAD model into a format I could work with and setup the lighting, materials and cameras
(3D Studio Max ages ago) — and design the artwork for the panels that brand the booth, in Adobe Illustrator and Adobe Photoshop.
