I have had a multitude of issues when trying to film my engines...for example, I film with my cell phone & get a call or text, the air conditioner/heater blower comes on, the neighbors dog goes into his need for constant attention & goes on a 30 minute barking session, I loud Harley rolls by, a farm tractor goes by, my wife interrupts my photo shoot by walking through the door & asking questions on the way in (she's much better about this now) ,the photo shoot lighting goes dead, the cell phone battery goes dead, & then we get into all the problems a steam engine will display at the exact wrong time.
