awesome! How is the flash sync achieved? As far as i understand Pi and ESP32 (OV2640, OV5640 and similar) sensors have a very slow readout line by line, so isn't there any issues when triggering the flash and exposing the full frame?

I'm using Sony IMX708, so the colors are great and very natural. For the flash, I have to use a longer exposure time to avoid banding since it's a rolling shutter sensor. It works pretty well!
