...but it seems highly heretical... ...It is very hard for me to fathom the notion of a robot with a lens on it... ...indeed 100% about "analog" photography.
In the studio I use a digital light meter... OH MY GOODNESS!!! I had no idea how bad I was being, I should be burnt at the stake!! ...sheesh, are you going to print the pics from your digital 'light meter'? Or sell the files? Or even show ANYONE?! If you're learning, in this day and age it's the easiest and most accessible way (with old Digi cameras going for less than any of my meters), so quit your puritanical belly-aching and get on with it! ...IMO...
My goal in life, is to be as good a person as my dog already thinks I am.
