Notes

I was wondering why in bulk mode over 30s the camera was busy after the shot for about the same time.
Now I got the answer!
When taking long exposure shots, we can have what's called hot pixels, red, green or blue. To remove them automatically the SLR takes a picture of the same duration with the shutter closed (called "dark" in astrophoto) and substract it from the previous. [1]
