iPhone Smart HDR captures more in difficult lighting, but the results aren't always better.

The edge of the sun in this image is more dramatic with Smart HDR, the normal version has a more pleasant fade to it.

iOS lets you save both photos, so you can choose which you like best. Open Settings > Camera.

Under Smart HDR, turn on Keep Normal Photo. You'll now get two photos whenever your iPhone uses Smart HDR.

Smart HDR works by combining different parts of separate exposures into one image. If you don't like it, turn if off.

With Keep Normal Photo enabled, the pictures will be side by side in the camera roll.
