Shadows - to use or not to use?
Shadows can give an interesting three-dimensional effect to objects on our presentation visuals. But too much use of shadows can make our visuals look cluttered. So we must be caution when applying shadows to text or images on our presentation visuals.
A general rule is that shadows are better applied to large objects. Applying shadows to objects that are too small will make the overall visual look cluttered. This is true especially for small text objects.
Another area where shadows will help is when there is not enough contrast between foreground object and the slide background. Adding a shadow in this case will increase the visibility of the foreground object.
Here are a few illustrated examples on when to use or not to use shadows on your visuals.
Use shadows selectively and when necessary to enhance your presentation design. Always remember that it is better to have clearer visuals that your audience can see than to have visuals that are complex and difficult to read.
