I hereby declare the 5th of every month CLEAN YOUR SENSOR day
A day when, no matter how much work your sensor has done, you get that shutter open and give her a damn good seeing to.
Havent got a sensor? Then its CLEAN YOUR LENS day. No lenses? Then what the fuck are you doing here.
Its time to shift that dust bitches - get to it.
