+ @brief Provides easy (high-level) access to some Exif meta data.
+ Please keep in mind that these accessors are provided for convenience only and will return expected/desired
+ metadata most of the time. The accessors check several Exif tags and/or MakerNote fields, but in rare cases this list
+ of fields checked may not be complete (e.g. if a maker writes a new tag) and then nothing is returned. So there might
+ be specific cases where you will want to use lower level Exiv2 API functions to access targeted Exif tags and/or
+ MakerNote fields for more specific processing.
+ Please note also that lens name function uses some heuristics to reconstruct the lens name, which might
+ involve combinig information from multiple tags and interpreting numeric codes. While the heuristics try to cover most
+ cases, they can't be perfect and might fail in some circumstances, leading to imprecise results.
