saving lighting positions for reuse

Noobie here, I’m not much of a modeler atm, not a clue with lighting / camera rendering. I’ve setup a camera/sun position that seems to work for a test render. But if I wish to change the view to another angle I’ll loose this setup. Anyway to save setting to go back and repeat it?

Thanks

A few options

Keyframe the location and rotation of the lamp. Move to the next frame and reposition, then keyframe again.
Toggle between the two frames to switche between the two settings etc
or
Add emptys at the different positions and angles. Then copy the location and rotation settings from the empty to your lamp
or
Add a set of lamps to a group. Add the other set of lamps to another group. Turn on/off visibility/renderability of each groups to switch between them
or
Add one sett of lamps to a layer. Add the other set to another layer then turn/on/off each layer to switch between the two

Richard, thanks this is a little over my head atm, but as I get the time I’ll try to work it out.
