Allan's spot on the money.
Personally, with the DSLR, after taking a RAW image, I would check the histogram in Digital Photo Professional. I try to ensure that the histogram peaks along the x-axis somewhere between the 1/2-way to 2/3rds of the way across. Calibrating them with appropriate length dark frames and then median combining has worked a treat for me.
Of course, with the STL this is going to be a new trial and error experience for me; Pete's beautiful lightbox will be of help here.
