Just as a private pilot can fly between his
offices in different cities for business purposes, he can fly for the
purpose of taking pictures.

Negative, IMHO.

In the first example, the flying is INCIDENTAL to the business. (this
is a key point)
He is using the plane as a car in the sky to get from office to
office.

In the second (assuming you mean he was engaged by someone to take
aerial photographs for a fee) the flying is NOT
INCIDENTAL to the business. It is INTEGRAL. He is now using the
airplane as a camera platform, an essential component of the business.

Commercial.
