Open the settings application in your iPhone.
Scroll down and select camera settings.
Deselect the Auto HDR feature.
Select HDR at the top of your iPhone camera screen.
If the HDR is functioning, you will see a small yellow box labeled "HDR." You're now ready to start taking some beautiful High Dynamic Range shots with your iPhone.
