I was asked by Davison Williams Creative Agency to render visual mockups for promotions they were working on for Grolsch lager. Sketched visuals were supplied to me and realistic photoshop renderings were required to show the client. The items included a reversible t-shirt to go with a flip-top style bottle and a beer mat lamp which was activated when a bottle was placed on it.
Photoshop was used in combination with other software to achieve the desired results.
