Just in case you don't end up using DSS I'd like to clarify for you...

You need to subtract reduction frames from the raw images that come down from the camera, before any processing is done on them. That's before cropping, rotating, aligning, brightness/contrast, anything!

By "reduction frames" I mean: Dark, Bias and Flat. Dark being the most critical but Bias and Flat also help when you get to the stage of being able to incorporate them in your process.
