When you say you only get 30s in live view, do you mean the maximum duration for the shutter to remain open?
If so, you can switch the camera to 'M' (manual) mode, dial in the f/stop required and then keep slowing the shutter speed down until 'bulb' is displayed. When used with a cable release you can then hold the shutter open for as long as you require.
That is totally different from mirror lock up though. Mirror lock up works by eliminating any internal vibrations from the mirror opening inside the camera which can affect sharpness. When enabled you focus as per normal, then the first full press of the shutter will flip the mirror up and after a second or so you press the shutter button again and then the sensor is exposed. To get the most out of it you need a cable release as pressing the button will cause more vibration than the mirror anyway.
thanks for that, the 30s is the ammount of time live view is open from your last command,
Hope that helps?

That still has mirror slap though, which is the point on mirror lock up. It does make a difference although granted probably not enough to be noticeable on a d3100.
so would a good technique be, go in live view, which will lift mirror, dial in settings and fire away,
the only prob i can think of is not being able to see the screen in bright light
But live view drops the mirror again and relifts it. So defeats the object. Its no different to shooting normally. Infact probbaly worse, as the mirror has even more movement and will take longer to settle.

You know Tom, I just got the camera out and tried it as I thought in Manual focus you could work around that in live view.
