This chapter has broadened our view of the things cameras can see. We have considered video capture at high frame rates and at wavelengths of light that are invisible to the human eye. As programmers, we have learned to wrap a third-party camera API in a way that allows us to use industrial cameras and OpenCV-compatible webcams interchangeably, thanks to Python's duck typing. As experimenters, we have extended our study of Eulerian video magnification into higher frequencies of motion, as well as more surprising patterns of pulsing light beyond the visible spectrum.
Let's reflect on all our progress. From finding the head of SPECTRE to exploring the electromagnetic spectrum, our journey as secret agents has taken us far. At this proud moment, however, our adventure must reach its conclusion. We will meet again. Look out for future books, webcasts, and presentations...
