Do not underexpose.

So i recently read this post where this dude say that he underexpose his photos and then adjust in post. Nothing more wrong. I mena one of the first thing that i have learn is that overexpose is always better. It will give u a lot more data and also it can reduce the noise. If u overexpose and then turn the exposure down in post will give you less noise the doing the other way. If u don't belive me u can see for yourself that overexpose will give u more data, just take the same photos with different exposure and see how much MB is the file size. U just have to know how much u can push the sensor untill it really clip the higliths.

EDIT: Some peaple didn't get this so i try to accentuate. U don't have to clip u stop just before.
