Is our noise measurement affected by temperature?

I’ve read a lot of articles about image sensors over time. Many of them were talking about something called “dark current noise”. dark current is electrons that are captured by the sensor but not as a reaction to light. This is actually unwanted signal the sensor has picked up. This unwanted signal has a fluctuation, […]

Canon EOS 400D vs. Canon EOS 30D Studio Scene – High ISO
