In many countries the advice is not to photograph infrastructure (bridges, dams, etc.), as it is illegal.
Examples:
> Photography: Taking photographs of UAE military facilities, sensitive civilian sites, airports, some beaches, or foreign diplomatic missions – including the U.S. Embassy or Consulate General – may result in arrest, detention, and/or prosecution by local authorities. Travelers should be aware of signs which indicate where photography is prohibited. Note that it is illegal to take photographs of other people without their consent. In addition, engaging in mapping activities, especially mapping that includes the use of GPS equipment, without coordination with UAE authorities, may have the same consequences.
> Photography: Photographing military installations is forbidden. Individuals have been detained and/or had their cameras and film confiscated for taking pictures of hospitals, schools, bridges, industrial sites, and airports. Sites where photography is prohibited are not always marked.
