I find sometimes having the camera enhances the moment. It helps me to focus on details and look at things from different angles, thinking about how/if something can make a good photo. I also like to put photos together into sets, so I will be thinking about things like how the detail on different old building compares, or finding all of the individual flowers in a garden as well as looking at the overall view. Then when I get back home and go through all the pictures to put together an album for the day it both helps to solidify all the memories and gives me a nice reminder to look back on.

I think the problem is that a lot of people take a photo instead of really looking, just as a way of ticking off a box of "I went here". Or they are just focussing on taking pictures of themselves, and wherever they are is just a backdrop.
