Take the shot now for an example. Older Canon sensors have a hard time when it comes to push raw development.
Just as an experiment and because I was too lazy to bring a tripod all day, here's an underexposed shot so I could take it handheld, where in Lightroom the exposure push corrected.
This shot is a single frame. What follows is a stack of 10 images of this shot where I tried to average for the noise.
Exposure set +2.08, Shadow recovery set to +74, some more settings that rather don't affect noise, default detail settings, jpg export, quality set to 66 percent, scaling set to 3000px longest side.
