1. A method comprising: accessing digital sensor data generated by an image sensor, wherein the digital sensor data describes light sensed by the image sensor; accessing image version data associated with the digital sensor data, wherein the image version data indicates that a previous version of a particular technique was previously used for interpreting the digital sensor data to generate a previous version of a digital image; determining that both the previous version of the particular technique and a different version of the particular technique are available for interpreting the digital sensor data; determining whether input has been received that selects the different version of the particular technique for interpreting the digital sensor data to generate a new version of the digital image; if said input has been received, then generating the new version of the digital image using the different version of the particular technique; if said input has not been received, then generating the new version of the digital image using the previous version of the particular technique; wherein the method is performed by one or more computing devices.
