I absolutely love his comment about shooting digital as if it were film. That's what a lot of my friends and I do.
The camera in totally manual mode. The only concession to automatism is using back button focusing, because aging eyes need a bit of help. But we set the focus before final framing, because it allows us to select the focus point and work out DoF for ourselves.
Using the light meter in spot mode has both the advantage of not having to carry a separate meter but, allowing you to meter for the zone system. This is an amazing advantage of digital over small format roll film. Every image can be measured individually and exposed to optimise the available lighting against the dynamic range of the sensor, which varies with the chosen ISO. Then, in "development", you can bring out all that lovely detail in the digital image, just like you could with film. The only difference is that film has to be exposed for the shadows but digital has to be exposed for the highlights. Just as with sheet film that can be individually developed to compensate, so can digital be developed on a frame by frame basis - something that roll film cannot easily do.
Taking this manual approach with digital has been revolutionary for our photography. Try it. But don't forget that the skills required are sometimes more than anything you've ever learnt from film.
I use a Nikon D850, but it might just as well be a box Brownie. It will more than likely be the last camera I will buy because it does everything I need it to do. When I unwrapped it, the first thing I did was read the manual and find out what was automatic by default. Then I turned everything off.
Why spend so much money if I didn't want all the bells and whistles, you might ask. Simple. I adore making large prints and 46Mpx makes that possible. The only thing that tempts me from time to time is a tilt/shift lens, but then I regain my sanity, realising that I really don't take that many architectural shots and those I do take can be corrected in post processing, was long as I plan for what the crop might remove.
@Martin Henson thanks for posting this video. I hope it inspires those who don't want to use film to slow down and improve their photography.
Oh, and the ultimate challenge is to go out with a digital camera and only take one shot, which you don't look at until you get home.
