Use PhotoIRmote to take long exposure photos.
You can program your intervalometer and set a long exposure time in order to take long exposure photos.
Look at this 8secs photo.
PhotoIRmote is not intended to be a self remote, but you can use it like that if you want!
We are developing PhotoIRmote.
This app will allow you to use your smartphone as a intervalometer or remote for your DSLR camera.
We just have to solve some problems and it will be ready!
