Search by Camera in Google+ Photos

Google+ Photos has a sophisticated search feature, but some of the features aren't easy to find. For example, you can search photos by camera. Use queries like #canon, #nikon, #sony, #apple, #panasonic, #samsung, #nokia to find photos taken using a phone or camera from one of these companies. You can also use the name of the phone or camera, but not all of them work. These worked for me: #iphone4s, #iphone5s, #canonpowershots95, #canoneos, #dsc-w150, #k800i.
