Here we go again with another example of someone not liking something and wanting to ban it for people that do enjoy it. The practice of taking pictures and using ones phone does not infringe on anyone else, yet because this person doesn't like it then nobody should do it. Probably doesn't like selfie sticks and people playing Pokemon either. This may improve the "Guest experience" for you but diminish it for far more people.
This is pie-in-the-sky but I think it would help a great deal if people actually learned how to use the equipment (camera, phone, etc) which they are using.
First, realize that the picture you're taking on a moving ride (assuming something like Haunted Mansion - not a speedy ride where you could drop your phone and possibly injure someone) is going to be crappy. Those pics you take at the concert: crappy. "Those blurry human-looking things on that platform are Pearl Jam! YEAH!!!" It's a crappy picture and not something you're likely to go back and review/treasure in the future but, instead, just you letting everyone else know "you're there".
For concerts, I don't get why bands don't let people take pics/record. It seems like free advertising. Yeah, you may get the odd guy who wants to watch the concert for free that's been recorded off a mobile phone but that's not the greater population.
Mobile phones aren't "bad".. Cameras aren't "bad". I do wish people would learn to:
- turn their screens all the way down in darkened environments. I don't like having this blinding light up in my face.
- hold the phone discretely instead of way up in the air blocking other's views
- learn to (not) use the flash/light.. So often people just leave this on "auto" and never have an idea that it actually makes no difference in recording, say, fireworks and, if anything, gives you that weird haze because the light is reflecting off the particles/humidity in the air around you.
A lot of it really is just: educate yourself and be courteous. Do that and a lot of these issues go away.
