Hi, I have been learning the back yard imaging basics with using a toucam through K3ccd tools, has been lots of fun and the odd frustration

that everyone seems to go through.
How do we know exactly what the shutter speed is when we move the shutter slider around on the K3 picture window, i cant seem to find any numeric representation for the setting, is this normal ?? do we just guess the speed and set it to the desired level via the light meter and on screen avi display?
Any advice welcomed
