I just wrote a blog article about this, last week, and have yet to post it.
While I don't as of yet have a good alternative for the word "analogue," I think that the term "Boolean" is a better descriptor for electronic photography than "digital," it being George Boole who codified Aristotlean logic into mathematical symbology that has become the basis of electronic "logic".
When we employ the term "logic circuit," for instance, we are saying that the circuit in question operates under principles of Boolean Logic, which is not necessarily "digital". Truly digital circuits employ Boolean Logic to encode data in numerical form (such as BCD - Binary Coded Decimal, or PCM - Pulse Code Modulation, or the output of an A-to-D converter, a serial bit stream of numerical information), whereas circuits employing logic gates (AND, OR, NAND, XOR, etc.) employ Boolean Logic absent numerical digitalization.
All digital circuits are Boolean, but not all Boolean circuits are digital, digital being a subset of Boolean.
