Custom installation made for internal xmas party, done with use of budget rpis and standard cameras. Animated GIF – as a result – had got good quality versus price, very accurate synchro time. White ballance was a bit challenging and IMHO it requires better selection of lens. I have used 5 rpis 3B with standard cameras, one server on macbook with ubuntu – all connected in LAN via cables. The most important think is to have all cameras calibrated in center point. All software was wrote in Python and is easy extensiblle to large number of cameras. Basic x-flo lights were used to have 1/250 shutter speed. See You next Xmas !
