Those forward voltage deltas are pretty small, and hard to capture with the limited ADC on most mcu’s, leading to low resolution readings. Timing reverse-bias decay with the input capture unit on an Arduino provides much higher resolution readings without any amplification: thecavepearlproject.org/2019/11/04/single-diode-temperature-sensor-with-arduino-icu-via-reverse-bias-leakage/

you should learn to point the camera to the right place when filming something
I don't mind at all
