So I wanted a remote shutter release for my camera, something simple/quick and easy to use - I didn't want to need to get my phone out or need the complexity of the Sony apps tethering with the phone etc. So I made one, emulates the shutter button press on a Sony bluetooth remote:
As it just emulates the shutter button, you can still shoot on timer or continuous etc, just setup the camera like that. I primarily made this for shots like my twin bridges one above (taken with this) where I have a long lens on a tripod.
It's not on the App Store or anywhere people can get it*, just thought people might be interested to see it.
*cos that'd cost me money to do, and this is way too niche to ever make the money back IMO. Maybe I'll open source it so at least people with the means to build apps can use it.
