Difference between lamp brightness and exposure slider

[Jstar]

I am currently trying to scan 35mm slides (Kodachrome, I am using a Kodak Kodachrome Q60 It8 Target.). After doing a prescan the image is too dark. I can adjust the overall brightness of the image by going to the options menu (special) and increasing the lamp brightness or I can increase the exposure slider in the picture settings windows. Are these too adjustments doing the same thing? What is the difference between the two adjustments? Will either adjustment require me to do a new IT8 calibration using same values when creating the .icc profile?

Dear Jstar,

the difference between both sliders is very easy to explain.
As you allready pointed out both will achive the same goal
the difference is that the Exposure Slider is increasing the exposure by adjusting the gradation curve
while the lamp brightness is actually changing the brightness of the lamp.
You do not need to recalibrate the scanner.
