High Dynamic Range Photographs
A normal digital camera sensor cannot capture all the detail in a scene some parts will usually end up over-exposed, or some parts might be under-exposed because the sensor has low dynamic range. However, by taking three different shots, merging them into a high dynamic range image, then employing some digital trickery to reduce the dynamic range without noticeably losing detail it’s called tone mapping, you can bring out all necessary details in a scene.

If you have set up AEB on your camera, then just fire off three shots in a row. If you don't have AEB, then take a photo; adjust the shutter speed one or two stops faster.
Experiment with algorithms and their parameters on a reduced-size version of your image you can pick a smaller one from the dropdown box of different sizes near the top left. Tone-mapping is a very mathematically demanding operation; the Mantiuk algorithm can take many minutes to render a photo at full size on slower computers, but only a few seconds to process a 256x170 version of the same. And there are things you going to need along your journey; you will need a camera with either automatic exposure bracketing, manual exposure compensation, or manual shutter speed control. A
tripod, if you have one or a solid surface to rest on if you do not.
You would also need to get a photo editing software, which will make your job easy when you need to do some touch ups there and there. While online also check out
