Honestly, that is probably the most overrated and exaggerated point in current film discussions. Because for more than 30 years now we have really excellent built-in exposure meters (and of course excellent hand-held meters), several built-in metering modes in cameras, very precise shutters, semi-automatic or automatic modes and so on, all of that making it so extremely easy to get a correct exposure. Even for total beginners with no knowledge about film and correct exposure.
I started shooting reversal film at the age of 14, with my first own camera, a Nikon FM (still have it). It has a quite simple 60/40 weigthed metering. Nevertheless even for me as a beginner it was easy to get 95% correct exposed transparencies.
Now with my F6 I get 99% perfect exposed shots, and the 1% rest is only 1/3 to 2/3 stop away from perfection, but still very good and usable.
My Mamiya 645 Pro TL has also a very precise metering, and with my TLR I just use my Gossen Digipro F2 hand held meter.
So no problems at all to get perfect exposure in medium format either.
With all these excellent metering tools we have today it is really extremely easy to get perfect exposures
All true but nothing that can be compared to color negative film tolerance to overexposure. 2-3 stops is like nothing (done and checked) getting additional shadow information if needed, and you can go even higher to 5-6 stops loosing very little highlights information compared to the hughe overexposure. When I load Portra 400 in my camera I know I am ready for anything.
When you are in Germany next time let's meet, and I will show you some examples. You will be very impressed, promised.
That is a very kind offer, I would love to see those prints. It will very difficult to happen though, but just in case: Where are you located in Germany?
