First of all, thanks for the app. It's fantastic ..!


A small suggestion here, as I used the app during my wedding recently. I used it with my Nikon D5500, and the fact is that during the party, it crashed many times because of the live view. (the Booth had a huge success !)
It appeared that live view is quite "hard" for the DSLR and it had consequences on the whole process. Needed to restart the DSLR, pair the iPad again, the printer also, etc.
Once I disabled the live-view function, we had no more bugs.
So we used it like this. But live view is a nice feature, really...
So I came to the idea

As long as it could have a difference in the angle between iPad camera and DSLR, it could be calibrated through a first step in the process.
What do you think
