I need to take stereo images with good image clarity and close shutter timing.
USB web cams are an obvious option but they tend to have low clarity with lots of motion blur and synchronizing shutters from multiple cameras is not possible.
Modern action cams have API shutter control and good still image quality, but all that I have researched can only be controlled over their own wifi hotspot, preventing the processing computer from being connected to two actions cams simultaneously.
Tetherable point and shoot cameras are extremely rare, while DSLRs that support tethering start at around $500.
Is there a simple USB still camera available? Or an action cam or similar that allows USB tethering?
