Storing pics on iphone outside of camera roll?

Is there a separate place you can save photos that owuldn't be on your basic "camera roll" on your iphone? Like i have pics that i don't want with the rest of my pics if you catch my drift.

Go to photos. On the top left you will see a '+' icon. Touch. From there you can create a new album. Then go to the photo and move it into this album.
