HDR is a setting on the iPhone Camera app. The letters correspond Loftier Dynamic Range. Merely what does that hateful?

It means that your camera will process photos slightly differently than normal in social club to capture greater item from bright and dark areas in your photo.

The reflected light on the tabular array is sharper and the shadows are cleaner with HDR. Only the biggest difference is through the window. Accept a look at a crop of just that portion of the photo, and notice how the HDR version captured the texture of the snow and the house beyond the street.

And so what’s going on here? What is HDR?

Before it was a button on the iPhone, HDR was a photographic technique for dealing with tricky lighting situations.  Having both brilliant spots and shadows in the same frame can make it tricky to capture a good image – often, either the vivid parts volition lack detail, or the shadowy parts volition announced besides dark, similar in the examples below. In the first photo, the sky is washed out. In the 2nd photo, the landmass is too night to see any detail.

HDR Photography solves this problem by taking several different versions of the photo in rapid succession, and merging them together into a single image. Each version will be adapted to a slightly unlike brightness – so your iPhone will take one photo for the shadowy parts, and one for the bright parts. So it will merge the best elements of each of these photos together into a single photograph that has vivid detail all the way through.

Technically, the process is a little bit more complicated than this, of course. At that place are lots of apps on the market that process HDR images slightly differently, and they are worth exploring if you lot are interested in creating images like the one beneath.

But what you really need to empathize is how and when to turn HDR on. It all depends on the situation, so here are some things to keep in mind.

  1. HDR volition improve manyoutdoor and landscapes scenes. Because these settings often have both dark and lite areas, you will often lose details. Turn on HDR to compensate.
  2. HDR is smashing for making the most ofdim lighting. Just make sure you turn off the flash. Information technology won’t work well with the longer exposure.
  3. Considering it is taking several dissimilar images, HDR is slower. So if you are capturing amoving object, or you are taking several photos in quick succession, you should probably plough HDR off.
  4. HDR volition eliminate shadowy or washed out areas. So if you are trying to create a certain mood, or photograph asilhouette, y’all should turn HDR off.

Across that, experiment! At present that you understand what HDR does, it’s upward to yous to see how information technology affects your photos. Some photographers make their whole living shooting HDR images, while others never use it.
