Implicating high_angle_shot → high-angle_shot
Link to implication

Reason:

Low-angle_shot has a very useful implication (edit: ALIAS) that leaves out the hyphen (low_angle_shot), making tagging it less finicky since both ways of spelling are treated as correct.

The high-angle counterpart should therefore get the same treatment.

Was this supposed to be an alias?

Whoops! Yeah, you're right. The low_angle_shot thing too, that's an alias.
Don't know what went on in my head there.

+1 for an alias

Approved as an alias, (for standardization and because it's easy to typo.)

Right on.
