Thats great about getting back into this.

I would recommend that you try Dream Lights tutorials.  You can look at the first two for free, and even just sign up for a month to get everything, but there is a lot if you keep it going.  Also right now they are having a 50% off sale on the membership.

To see a list of the tutorials you get I believe you can go here.  About half way down the list you will see "Daz Studio for the Beginners" part one and two that you can get for free. (they are up to 12 videos in that series now).

You can also can get a free Light Dome for Daz Studio as well.
Hope that helps
