PERMANENTLY Prevent Photos from Opening Automatically

Hi All!

I just upgraded to Yosemite, and with that came the Photos App that replaced iPhoto.

The internet is full of forum posts asking how to prevent Photos from launching automatically when a device is inserted, and full of replies saying to uncheck the tick box in Photos for each given device... But this is no solution at all!

AFTER telling Photos not to open for a given SD card, if the SD card is reformatted in-camera, the setting is lost and Photos will open again the next time the SD card is inserted.

Is there any way to PERMANENTLY prevent the Photos App from handling digital media FOR ALL DEVICES by default? Any way to reset the default behavior in Terminal perhaps???

I am not the only Photographer who prefers the Adobe software and has a bag full of SD cards that get reformatted routinely. It is seriously aggravating to come back from a shoot with 8 SD cards full of new media and wait for Photos to launch before returning to the Adobe family of software to import media over and over again. It's a major workflow disruption!
