A few months ago, I photographed a product that was on its way to production. The product prototype was in the studio for one day before heading to China. The photo was going to be used on the retail packaging and web site.
Many weeks later, the product specs changed and a new photograph was needed showing the addition of a LED light and the top in an open position. Since, the prototype was thousands of miles away, I had to create add the new details in photoshop and make them convincing enough to use on packaging and posters.
