Software Benchmarks

1- Processing time

I’m really obsessed with the performances of our app, and I keep pushing my guys to improve the software as much as possible. There are ways to speed up things by having proper hardware, network configuration and proper settings. Once everything is sorted out, you should get results as fast as what we’ve been measuring here at the studio

2- Trigger precision (usb triggering)

Starting from version 1.11.0+, USB triggering through Raspberry Pi' computers OR using usb-hubs on a single Windows computer is about the same as using an analog trigger (using the trigger connection port). And that is true even when setting 4 cameras on a single Pi. From our experience, the only precision problem left is about the cameras themselves (mechanical shutter latency lag). Our latest tests have been made using Canon SL1/100d and SL2/200d, and we’re working on various test scenarios to provide you guys with more details.
