Using Adobe Illustrator I started by making line drawings of the shelves then added colors and textures in Photoshop. Took a pictures generic bottles, edited color, transparency, logo on them, and finally edited position and added shadows for final render.
Two denim display tables I designed that are featured in over 300 Macy's stores.
(EDIT: The last picture is from the model we used to make the signage, who saw the table at Macy’s, and took a picture with it.)
