Traveled to Mount Kraken Rope Bridge again (where I did the Blacktail quest) and got lucky to find whitetails directly. Just place a waypoint marker on the map after you have spotted the animal to get an accurate distance if you do not have a range-finder.
After 5 failed attempts I finally managed to get a photo of the bear that actually passes the mission. The mechanics of this mission will make you doubt the correctness of the game, i.e. you have the bear fullscreen on your camera and still it fails to complete. The quest is doable, and feels bugged but just stick to it and you will complete it!
The key to this mission is to sneaky sneaky closer then you would expect, and once you click a photo with your camera, Mr Black will notice you and run away and you have to start all over.
In the successful attempt I crawled to about 15 meters from the bear and once it stood up, I got into a crouched position with the camera and clicked photos.
Mr Black attacked and the mission did not complete until I clicked more pictures during his attack, lucky survivor with 3% health left and a completed mission!
Ah, another night hunting mission... This time to down a Blacktail Deer with a .44 revolver.
Biggest part of this quest for me was to level up hand-guns so that the 44 was unlocked. This took ages.
The actual completion of the mission was just luck... Was doing another quest and the night went out in the evening and suddenly a Blacktail Deer called really close to my location, quick stop and use a deer caller to get its attention. When it appeared, one shot in his spine and harvest to complete the mission.
Hope this helps anyone that got stuck on this mission
