I've been experimenting with using slideshows as a way to conveniently package larger pictorials for a while now; it wasn't until I was looking at an action-oriented set I'd done that 1 variable could make a lot of difference - the length of the slides themselves.  Thinking about it, giving all my pics an even 5 seconds failed to do justice to the ones I really wanted to stand out; some work better as setting the stage with a few quick shots before the one you want the viewer's attention to really linger on.

It's one lesson I'm definitely going to carry on in future photo shoots
