Just took me 5 trys to get all dust spots gone.

I use the blower thing and displace the particles with disposable sensor swabs. Looks perfect, go outside and look around at the sky with it. Go back and put it on my 32 inch monitor to inspect. Huge dust spot appears out of no where. Repeat 5 times until no more dust spots.

Go do real estate shoot, look at footage, huge dust spot.
