Back in design school, making our projects was fun; photographing it for our portfolios was not. An expertly-shot photograph of your prototype will make all the difference, but while we had plenty of instruction on how to build that prototype and make it look convincing, we had little instruction on how best to manipulate light in a photography studio.
We could've learned a thing or two from Canadian photographer Michael C. Eng, who's licensed some of his photographs to design consultancy Ziba Design. Check out his excellent work here. His lighting, depth of field, and composition all make these products look even better than they do in real life.
