Hello there,
i think it would be a cool feature to trigger a photo once a loud noice
is received by the build in microphone. It could be used for:
a) highspeed photography
(to shoot a exploding baloon or a crashing glas bottle)
b) remote trigger
why use a cable remote if you just need to clap your hands?
Especially for highspeed pictures this way seems to be much faster
than motion-detection since less calculations have to be made (at
least I think so)
Best regards
careyer
