How can I hide the icons on my desktop?

Hello,

I am using OS X Yosemite version 10.10.4

Recently, I have updated my desktop with a wonderful photo that I am very fond of. It is wonderful to see it in the background but I would occasionally like to show it full screen without all the desktop icons or dock cluttering the view.

Is there a way to briefly "hide" all the desktop icons and dock or, conversely, click on the desktop image so that it is displayed in a full screen manner?

Thanks,

Vince
