As soon has I started playing the game, I immediately begun to take pictures. That's because Days Gone's photo mode is the most complete and fluid that I have ever seen in a videogame. It's even better than the Assassin's Creed Origins' one, my personal favourite.
The highly detailed graphic permits to take a lot of intresting photos. The roads are hyper-realistic, so my suggestion is to make them the main protagonist of your shots. Them or Deacon, that is detailed as well. Also, landscape photography is something that you want to try.
