Dave in California asked:
Are the verticals on drone images suppose to be the same as the verticals taken at ground level. That is, how important is it to keep verticals vertical as in other areas of real estate photography?
My take on this question is that if the drone image (still) is being used as the primary front exterior shot then all the same real estate photography rules apply - don't have wonky verticals that distract viewers attention; but if drone still images are used in other than the primary exterior image and it's not a big deal to have wonky verticals. That said, look at Grant Johnston's drone moves that he demonstrates in his drone training video above. Almost all of the verticals are dead on!
