You sure can! 

After taking the photo with your phone (or other supported device), put it on your computer and upload it to Postradamus as any other image.

Send the post from Postradamus to Facebook, and Facebook will automatically convert your 360-degree photos to 360 Photos.

These photos need to be created by using specific devices, apps or software:

360-Enabled Camera

Take a 360 photo using one of the following:

  • Ricoh Theta S
  • Giroptic 360 Cam
  • Samsung Gear 360
  • LG 360 Cam
  • IC Realtech ALLie
  • 360Fly
  • Panono

iPhone or iPad

Take a panorama using one of the following:

  • iPhone 4S or newer
  • iPad mini 2 or newer
  • iPad Air and iPad Air 2
  • iPad Pro

Samsung Galaxy

Take a panorama using one of the following in Surround Shot or Panorama mode:

  • Samsung Galaxy S5 or newer
  • Note 3 or newer

Photo Sphere Apps or Devices

  • Take a panorama using Street View, Google Camera, Cardboard Camera or Theta S.

Image-Stitching Software

  • Stitch images together using software like PTGui.

Also note that if you upload a panorama that's wider than 100 degrees, it may still automatically be converted to a 360 photo.
