Taking an iris photo is very easy. You can use a camera or your cellular phones camera.

If using a camera, use the macro setting and auto-focus. On your cellular phone, use the macro setting if available, zoom in for a nice focus. It is best to use a flashlight for lighting on a side angle (do not shine directly into the horses eye). When ready click to take photo.

***Please note: The first time the horse hears this "click" it will startle him/her. After this you will be able to take as many photos as you want without startling him/her. This will happen on both the right and left side, as the horse needs to remember the clicking action in both hemispheres of the brain.

Detailed Iris Photography Instructions from Jack Colburn

  Helpful Hints:
  • A.M. light preferred (before noon) or very a specialized lighting system for your camera.
  • Use good handler
  • Each eye photo ‘new experience’ to the horse.
  • Back light problems with background reflection: Best standing with your back to neutral color wall
  • Shaded if possible with horse at an angle toward camera

Order To Take a Picture - 1)wall 2)Camera person in place 3) Camera ready 4) Horse Handler
To clarify, choose your wall to stand against, position yourself with your back against the wall, get the camera set up then have the handler bring the horse up to you while you focus on the eye.

Camera Settings

  • Manual setting with flash setting on
  • Manual setting (no auto focus) preset to show complete eye
  • Move slowly toward eye and when in focus snap photo
  • Drawing camera in and out to focus is disturbing to the horse
  • Shutter speed 125 -If you need more light shutter speed 60
  • F-stop = Very dark eyes 8 to 11
