- Lightmeters! Tricky, but simple devices we give too much credit to, forgetting to switch on the most precise tool we have: the brain!
Here I will explain how those "magic" thing are made; how they are calibrated as well as giving you some warnings on their use.

Great Andrea!
Come sempre una spiegazione perfetta
La Bibbia. Grazie Andrea.
Felicissimo di aver trovato questi aggiornamenti nel canale.
Eccellente tutorial, grazie Andrea!
00:01 📉 Light meters indicate middle gray, not precise exposure.
00:33 📏 Light meters suggest exposure but only target middle gray.
01:43 🛠️ Light meter components include a metering cell and variable resistors.
03:29 ⚖️ Metering standards vary; some use 18% gray, others 13%.
04:08 🔍 Four metering patterns: average, center weighted, spot, and matrix.
07:09 📊 Reflected vs. incident light metering: each has different advantages and limitations.
09:29 🧠 Reflected light meters require interpretation; incident meters suggest exposure.
10:35 🌘 High contrast situations can challenge incident light meters.
12:26 🎯 Correct exposure focuses on shadow detail, not framing.
13:44 🎛️ Spot meters measure narrow areas, useful for precise exposure settings.
16:07 📸 Spot meter settings guide exposure based on shadows and highlights.
17:23 🎨 Technique is a tool for expression; there’s no universally "correct" image.
18:10 🧠 Use technique creatively rather than following strict rules.
Excellent! It seems you really watched till the end getting the useful points.
Of course everything must be calibrated. The -3 +3 readings are always the same but what changes is the effective iso speed that you set in the meter and the developing time (energy). Also the middle gray reading...it gives the middle gray if you calibrate the whole process to give you the middle gray. Am I right?
Yes, correct. BUT it is more convenient to calibrate on the deepest shadows, because calibrating and thinking on midtones may produce big mistakes in exposure, ie: increasing under exposure as contrast rises.
Thank you but turn off the music.
