Given the stunning vistas and huge scale of Dubai, it is very tempting to just run around taking as many photographs as you can. However, it will be extremely important to keep in mind that many people place modesty and safety above all else and therefore dislike having photos taken of them, without consent.
Taking the effort to make sure that no one is in your shot prior to taking the picture can go a long way but many people simply suggest that you should commit the sights to memory or simply just spend time observing it while you can.
