Any travel photographer, or traveller in general, will tell you how important it is that you respect the locations you are exploring. This applies as much for natural environments as it does for sacred manmade spaces, and it's the latter of these that are having to ban photography because of rude tourist photographers who are ignoring this fundamental rule.
Would you like to photograph the Upper Yosemite Falls by drone? Attach a GoPro to your newly-acquired DJI Phantom 2 and just have at it, capturing views that Ansel Adams would envy?

If you're planning to attend the Kentucky Derby early next month, you might want to make sure you'll be content with capturing your memories with a smartphone or point-and-shoot.
