Narrative:

A C172 was transitioning VFR from the southeast to a photo site northwest of the field. A C525 was issued departure instructions off runway 16; with a left turn heading 030 and to maintain 2;000 ft. Traffic calls were issued and both pilots advised the other in sight. I also had both aircraft in sight. The C525 did not make any drastic maneuvers or climb out of assigned altitude. After the C525 was past the VFR C172 he changed to departure without saying anything about the other aircraft other than he'll avoid him. It was not until later in the day; when the atm called the tower and advised the controller in charge to start paper work we're we aware of the pilots desire to file paperwork for a near mid-air. Traffic calls were issued. The pilots saw each other. And the tower was providing visual separation.
