Dexim ad vs Jamie Nelson - This is what we call "demo love" - and what lawyers call "copyright infringement".

Last year I worked at a place where the "creative" was limited to "Model on the left, product to the right" and every single sketch ever made had to be done in photoshop so that the myriad of people who had something to say about the layout in its infancy, could waste everyones time complaining about "the models ears being too square" because all I found was a photograph of a great face with big hair, and my lassoing away of the hair left her ears looking silly. (Yes, I had to go draw fake ears on the model for the next meeting, Seriously.)
Using pre existing photography for presentations not only locks you into working only with what already exists (and that you can find) instead of using that creative brain they hired you for - but also puts you straight into the path of copying work which is called derivative work and can get the company into serious trouble. Y'all do remember that little thing called "copyright", right?
At that job, I did what any sane AD would do, I went back to pen and paper and drew everything I had planned to be in the final layout. That's when some people turn to already perfect photography to present to their clients in meetings instead. And that is when shit like this happens, where Jamie Nelson's bright yellow photo is copied to a T for Dexim.
