Scripts

If you don't like having files named IMG_1234.JPG, you can try sth like this to rename the images _yyyy_mm_dd-xxx.jpg_

j=1;
for i in *.JPG;do
   exif.py $i 2>/dev/null |\
   gawk -v i=$i -v j=$j '
       /DateTime:/{
           match($0,/([0-9]+):([0-9]+):([0-9]+)/,a);
           system("mv "i" " sprintf(a[1] "_" a[2] "_" a[3] "-" "%03d" ".jpg",j))
       }';
   j=$((j+1));
done

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]
