At present neither shutter count nor the iPhone serial number are embedded in iPhone picture metadata.
Is there an app for that?
Reason: Pictures come into a database from multiple sources. Using the date/time stamp already gives collisions due to camera burst mode, and multiple photographers. I would like to assign each incoming asset an asset number composed of model+serial number+shutter count. This generally works for mainstream cameras, but it doesn't work for iPhone. Is there an app that would add this in automatically?
