For folks buzy with the World-photographer, today is one of the two days a year you can get 3 stars for this photo. Be sure to activate real time when flight is started. GL.
Or if you want, you can just change your time and date in the windows settings of your computer. This way I managed to do all the photos/stars that needs to be done with real live time. 
For this one I turned on dev mode and I put a bison in the game myself, so that one I did in Free Flight. So dev mode on and then again change your time and date in the windows settings of your computer.
The only thing is you have to be very quick if you want to use this method. Be sure you are in the right position, just do a test photo if you get the other stars so you know you are positioned right.
Then is the moment you change the time and date in your windows settings, take the photo and then quickly change your time and date back to normal.
I had to do it few times I had to redo it like 4 or 5 times on some photo’s for it to register correctly and that it saved the 3 stars, cause I was too late.
So you could get an “big” error and then you just need to restart the game and in my case also restart your computer, cause the game wouldn’t start up. I called it the big error, cause then your only option is to go back to desktop and restart your computer, server error bla bla bla.
Or you get the “small” error, it just shows a little pop up on your screen that you are disconnected , but if you are quick enough, then after a few seconds it will show a green check marker and your back connected, if this happens you can try again and change back time., one time I got the small error 5 times in a row, I just kept on trying until it managed to save the 3 stars.
So if you want to try this, be aware you could encounter one of these errors, but you’ll get the hang out of it ones you know the timing.
