When you vacuum out your film holders - dont forget to vacuum out your camera! - also - you have a lipstick brush for your lenses .. right? -- brush off your film holders before you load them in your camera. I know that when you put that static charged film holder in the camera - it not only draws in the dust from the dark slide, it also sucks it in from inside the camera!! - Never fear - you will overcome these obsticals!
