What an awesome way to teach that lesson "When you say things in anger, they leave permanent scars just like these. And no matter how many times you say you’re sorry, the wounds will still be there.
I use Canon 80D + Tokina 11-20mm on 11mm to shoot 4 photos of f8 at iso 100 for ground and city and lights. For Milky way I had to turn 180° away form city where it actually was and it was much much darker location. I shoot with the same camera but f2.8 and iso 1600 for 25 sec exposure. Then I combine those 5 into single one. Hope you like it!
