This Photo Op in The Crew 2 is called home and filed under the weird section. To get this E.T. inspired Photo, you need to buy a dirt bike first and find any jump.
Bikes can be bought at the offroad dealer or at KTM in the menu. After you got a bike, make a jump with it and press Y/Triangle to get into the photo mode. If you current time of day is not night, then change it by pressing X/Square. Here the time of day can be changed just for this photo. Frame yourself in front of the moon and you completed the home photo home in The Crew 2.
