Great to hear that a principle my father taught me about 40 years ago when all we had was Manual shooting and focus (with his old Pentax ME) and fixed ISO (film) still comes round...at the end of the day you can't change the simple physics of how light behaves

That's absolutly true. My first camera was a yashika electro 35, 8 years ago. and it felt so right to start learning the true basics and techniques of photography instead of buying a digital dslr. Cameras now-a-days are great, no point of not saying it, but all the basics and techniques about light and exposure don't change over the years.
