1. A method implemented at a computing device using metadata and processing image data based on the metadata, the method comprising: identifying one or more tuning parameters by the computing device based at least in part on metadata associated with a geographic location associated with a user's account of a service provider that originates the one or more tuning parameters, the metadata being identified independent of a geographic location at which the image data is captured; and responsive to a user input, processing the image data by the computing device using the one or more tuning parameters that correspond to the metadata to change one or more visual characteristics of the image data in a manner that is likely to be consistent with a user's expectations based on the geographic location associated with the user's account.
