Eighteen megapickles is really a great size. I think one megapickle is more than enough.
Why 18? Well, apparently the folks at Canon take the Boss seriously. "18 till I die"...
Makes sense to me. I have been 18 for over 3 decades
OK guys, I don't care who you are, THAT's funny!!!
What you said makes sense. I can understand more why 18MP has been Canon's choice of sensor size.
