In this course I learned to take good pictures for prototypes or products to use for posters. I think this was very useful because in that way you can convince you customers even more of your product. In the assignment DG291 I already used some techniques I learned from this course for a poster. It was a way to make a smooth and equal background. You need a paper of A3 size and hold it behind the prototype in a quarter pipe hold. Furthermore I learned to fine tune the white-balance of a picture so that the picture will not be under or overexposed.
