“You often feel tired, not because you've done too much, but because you've done too little of what sparks a light in you.”
― Alexander Den Heijer, Nothing You Don't Already Know
Here is my data card from such a test series. I mounted a 35mm body to front of lens to get "quartz" controlled shutter speeds. That wasn't a totally bad idea but it caused vignetting that led me to conclude my EI should be 64 for TMY-2.
It was a lot of work and got me Tungsten test results.
I included reciprocity failure information.
One valuable takeaway from this test. You sure learn the logarithmic nature of exposure after making several runs of this.
A seven-dollar Stouffer scale is so much easier.
Who disturbs the peace as a pebble disturbs a pond? Ed Gruberman? The Zone System is a journey towards the horizon not for beating people up.
See if you can get ahold of a Kodak Professional Photoguide with the gray scale and gray card in it. It has 8 different tones. But remember, there are a couple of stops between shade and sunlight as well, so expose the scale in the shade and in the sun. Develop for the recommended time and temp and make a few contact prints with your chosen paper to get the information you are looking for. 1. Your negs were exposed for too long or too little, and/or 2. your negs were processed too long or too little.
The Zone System today is a wasteful distraction
Possibly, once you fully understand it and have practiced it enough to be sure of that. As a step up from taking a light meter reading and exposing at box speed, however, it has served generations of self- and professionally-taught photographers. Sure, eventually it starts to look like applied sensitometry with hard lessons about process control, but there are reasons why it was introduced so long ago and is still around today.
