When you make a digital sign here at the Law School, we ask that you submit two copies of the slide. A PNG and the “PowerPoint Original”. This is so we can whip up a few quick corrections, if needed.
This presupposes that you use PowerPoint to make your digital sign. In fact, this is what our latest round of training did. At that training I asked if anyone wanted to try a graphics design class to supplement this and go “to the next level” with better graphics instruction. There was some interest. I hope we can support that interest soon.
In the meantime, I ran across a quick eLearning article about how to make graphics in PowerPoint. I think it’s excellent. You might want to give it a try.
