How do you know when to use or not use custom animation and/or
transition in the presentation for maximum effect.
This depends on your purpose. Generally, you should be asking yourself if
you can justify using it, not just to use it for the sake of using it. If
everything flies in from the left just to be cute, you probably want to
skip it. Transitions effects from slide to slide are usually not too bad if
they are consistent and brief, but if they delay getting to the next slide,
they are probably a bad idea.
Many of the best PowerPoint presentations are more pictures than text (that
is, pictures that are meaningful and relevant) so animation can help
highlight the portion of the picture you are describing.
