Narrative:
Just after takeoff, a company pilot called on company frequency and advised that we were trailing a lot of smoke, but he could not tell which engine it was coming from. I immediately declared an emergency and advised ATC I was returning for landing on runway 24, we had just departed on runway 6. As I returned, I asked flight attendant and ATC to help tell which side was smoking. Flight attendant couldn't tell. ATC thought maybe it was the right engine. At the lower power setting, the smoke must have decreased. After uneventful landing, I shut down right engine on taxiway. Fire personnel observed no smoke, followed us to gate to continue to observe.
