Don’t take pictures of women – especially UAE nationals
You'll be offending a lot of women if you take their photographs. This is especially true in the case of Arabic/Muslim women because some consider it against their religious and cultural values.
If you do have to capture them in a landscape picture, asking for their permission prior to taking the picture will save you a lot of trouble.
Note: If a woman notices you taking her picture and asks you to delete them, oblige the request before she reports you to the authorities.
There are times when you may want to capture a picture of children or a group of people; make sure you are honest and tell them the reason for taking the picture. Ask for their consent and if you are declined, don’t push it.
Although a DSLR for a photographer is what clothes are to a body – inseparable – but carrying such a large camera will attract unnecessary attention and imply that the pictures are being taken for commercial purposes. Try and use the digital camera as much as possible since it is easier to carry and you can be discreet while taking pictures.
Ask nearby policemen to avoid misunderstandings
There are times when there may not be any signs to stop you from photography but the area can be restricted. For example there was a case when two locals were fined when they took photos of the Yas Marina motorsport racing circuit even though it is a famous tourist and public place. So it is advised to ask nearby policemen, security guards or representatives of the place before taking pictures.
Do not take pictures of Royal Palaces
There are usually warning signs placed around the royal places. But even if you don’t see one; do NOT take pictures. There have been many cases in which tourists and residents, in their innocence, click a few photos only to be fined by the authorities.
This includes sensitive and government installations, airports, and the military bases. There have been many cases where people were fined/imprisoned or their cameras confiscated.
Don't offer Arabs money for photos
Offering an Arab money for photos is considered an insult. Just ask for permission and most of them will be happy to smile for you. However, if you see any non-locals, laborers or workers, they'd be more than delighted to accept some money and pose for you.
