Order prints using the app PostalPix (from SalonSwipe) or mail actual postcards using Postagram Postcards (from Sincerely Inc.). The apps are free on the iTunes and Google Play stores but cost per photo sent. These services get photos out of the digital world and into the real one.
Check out Photojojo.com for ways to enhance your smartphone cameras with lenses, filters, boom mikes, tripods, etc. A set of three lenses that includes a macro, telephoto and fisheye lens will cost you about $49, for example. Another popular three-in-one lens set is the olloclip, available at www.olloclip.com.
