How to set a Coolpix P500 to Shutter Speed?

I'm doing a science experiment that involves luminol and in order to take pictures of the blue glow I need it on Shutter Speed. I recently got this camera so I am not that familiar with it. If anyone could tell me how to get to Shutter Speed that would be great!

Please comment on the Nikon P7000 or P770?

I'd like to hear from people who own one of these cameras, including pros and cons of operation, image quality, and low light performance.

I like everything about this camera except the size.Is it too big to stuff into a shirt or jacket pocket?

Thanks for your insight.
Added (1). That's the P7700. I didn't notice the missing "0."
