Customers may take photographs of documents on their own, with some limitations, provided that the photographing and preparing of documents for photographing does not damage the documents. Use of flash is forbidden. Customer use of cameras should not disturb other readers.
Exceptions include registers (or parts of registers) of personal information younger than 100 years: they may not be photographed. For private archives, the limitations (if any) set out in the handover agreement shall be observed.
Using a camera does not require specific permission, but you should always notify the reading room staff that you are going to take photographs of documents. Upon the notification the staff will check whether you are allowed to photograph them.
