buildings, especially tall buildings are pretty hard to photograph. one solution is if you can get far enough to get the whole building and some can be the best way. also then you can use some tools to straighten it up. every time you shoot up on a building it is really hard to get what you want :)
also there is a reason why people that photograph buildings for living often use tilt shift lenses
Not that is makes me be a better photographer knowing this, but it makes me feel a little better as it's not entirely my fault 😂
Getting far enough can be a problem, especially in old, medieval cities, where streets are narrow and buildings are tall 😧
Thanks for the tips, it means a lot as you're professional ❤️
