I want to be able to view what I am shooting on my Nikon Coolpix P600 camera on my computer before I take. Any tips on how to do this?
What you are looking for is called tethering.
As far as I know, no camera from the Nikon Coolpix Pxxx line can be tethered.
- Lightroom doesn't support it : https://helpx.adobe.com/lightroom/kb/tethered-camera-support.html
- The guys from controlmynikon.com aren't supporting it : http://www.controlmynikon.com/#!download/cdhg
- Same thing from digicamcontrol.com : http://digicamcontrol.com/cameras (only the control of some Coolpix - L830, 5400 and S5300 - is mentioned, but no Live view).
If you are not looking for viewing then shooting and can settle for shooting manually then viewing, you can use ViewNX2 from Nikon (http://downloadcenter.nikonimglib.com/fr/products/166/ViewNX_2.html) or a wifi SD card if using a cable is an issue.
Mostly DSLR can be tethered.
