Can you take photos on a aeroplane using a digital camera?

yes, but not when taking off or landing, only when airborne and fasten seatbelts sign is gone off

same applies to any other device ie laptop, nintendo etc

Yes just like the traditional type of camera - when the 'fasten seat belts' sign has gone off. However, don't use a flash or it will reflect in the window and 'white out' your photo.
Don't try to open the window for better shot either! lol

yes indeed ,i have seen many people clicking openly on regular flight to Austria but one guy took a snap of the cockpit while door was open and they made him delete it

Once the plane has reached cruising altitude and the pilot has switched off the seatbelt sign (in ireland/UK anyway). in USA i think you can at any stage. It's a pointless safety precaution if you ask me. with all the electronic shield these days i don't think it will cause radio interfernce.

Yes !
Just give me THE DIGITAL CAMERA.

yes but you may need to ask the cabin crew to ask the captain as its up to him nowadays but he usually says yes.

yes u can . depends on airline policy as to when. some wont let u use any electronics during take off n landing

why not

ya sure u can use your camera on air...they dont allow mobile on economy class but camera is allowed during flight

Yes but I always found a little bit hit and miss. Take lots and then delete the worst.
