Give photos on your slides a 5-degree rotation
When everything is proper and orderly, it can turn out to be uninteresting... boring... dull... uneventful... dry... clichéd! This is how I sometimes felt when working with photos on my presentation slides. It is easy to just drop a photo in the placeholder of the slide template. But we can go a step further to make the overall slide looks a little bit more interesting.
Select one or two of those photos and give it a slight 5-degree rotation, either clockwise or anti-clockwise. At the same time, assign a simple photo frame to your photos. An alternative to assigning a frame, adding borders and shadows to the photos will also do the trick.
The examples below will give you an idea of how the before and after will look like.
Be cautious not to rotate too much. A slight four to a 5-degree rotation is all that is needed.
