One of the things I've noticed about people taking pictures is that they are often scared to get close.
It's a big mistake, especially when taking shots of people.
90% of the time close-ups are much better. Extreme close-ups can be fun, too. 
You should try them, if you haven't. In this age of digital photography, it's easy to experiment.
Try animal close-ups, too.
Even if you have to use a zoom. Don't be scared. You'll be surprised at how much better your pictures are just by getting a little closer.
It works with everything. I love nature close-ups, too.
They usually say more than distance shots.
So who cares if your child says, "Mom, what the heck are you doing?" Do it anyway. You'll get some great pictures. Mine are so used to it that they don't ask any more.
Application to writing? Focus in on even the little details, things you wouldn't normally notice, unless you were very close up.
