How to stop photo sharing on apple devices?

I have 4 apple devices on my apple id. 2 ipads and 2 iphones.every time I take a pic on any of the devices they get put on all of the devices photo stream. How do I turn this off? Like if I take a photo on my iphone i want to keep it only on my iphone. I don't want the other 3 devices to see it.

Added (1). Ok but i want to keep it in my own photo stream so i can transfer the pics to my computer.

i had an iphone 4 and i just got the 5 and the 2 ipads and this is when it started. When i had the iphone 4 and the other iphone it never did that

When will the iPhone 6 be released?

I currently have an Android and an looking for an iPhone. I heard an iPhone 6 will be coming out soon, should I just wait or get like something else, I don't want to waste my money D:

**if I buy an unlocked iPhone with no contract can i upgrade it for some reduced price for the iPhone 6?

Just met a girl at a party, prob won't see her again, is it weird to email her?

I don't have facebook i felt weird since i didn't have many pics on facebook and never bother learning how to do profile pics and whatever.anyway we met at a mixer ( frat sorority mixing party)
the thing is our frat sorority arent' close we mix once a year b/c its a rule or something. So is it weird to email her asking her to play tennis or something sometime?

i'm thinking tennis bc she played tennis in high school and i did too. And is it creepy only if she didn't seem interested? I mean she seemed really interested in me. We played beer pong for around 30 minutes together talked a lot and for some weird reason she took a selfie picture of us together to send to her friends? I think its an iphone app.

so would it be weird to email her? Thanks!

Added (1). How would i call her? And why did we take a picture? And how do i talk to her if i might never see her again?

IPhone text messages not working?

I was able to text this person earlier today with no problems. The text boxes were blue, meaning we were using imessage. Now, suddenly my texts to this person are in green, and it then said under the text box "sent as text message", as opposed to "delivered" when it was blue.

Now, my texts to this person are still green, but it will not even say "sent as text message". Nothing comes up at all.

Texting and calling everyone else in my contacts works fine, as does my cellular data with internet browsing etc. Its only this number I'm having this problem with. I'm not sure if calling this number works because I have not tried it.

I have checked, and the SMS, MMS, and immessege options are al turned on in settings. I have tried restarting the phone, re-installing the sim card and even calling at&t tech support.

Any ideas?

Thanks.

BTW- I have a 4S, and I'm not sure what version this person has, but I know its an iPhone.

How to start an iphone 4s up without a sim card?

I just want to be able to use it as an itouch, rather than the phone service and it will not let me restore it to that option. It is restored and it lets me choose my country(usa), language, Wi-Fi, and then it tells me to please insert a sim card. It tells me the same when I plug it in my computer with itunes. Once again I just want to be able to use it as an itouch.
