ok I understand how Baird got his first pictures to work using an LDR and have an idea how normal film cameras work. But how do modern electronic / cmos cameras work, please?

In a charge coupled device (CCD) camera, each mix has a small phosphor which emits electrons whenever it is exposed to light. Those electrons are used to charge a small capacitor behind it. The capactor stores the charge until, after the exposure, an analog to digital converter digitized the voltage on the capacitor (which is proportional to its charge), and stores the data in flash memory.
