I think Sidharth asked some time back about digital photography during inspection.
Here is a very relevant order by CIC WH: http://cic.gov.in/CIC-Orders/Decision_03082006_1.pdf 1. Whether videography can be permitted. 2. The status of providing information sought by the appellant. On 1) above, if an applicant wishes to make copies of records/ samples given to him for inspection at his own expenses, it is not for the Public Authority to object to the form in which the copies are being made, provided it is restricted to the information permissible under the Act. There is no provision in the Act disallowing Videography, and therefore, cannot be excluded unless it violates the parameters of any information sought and agreed to be provided.
