High Dynamic Range Imaging or HDR abbreviated stands for high dynamic range photography. If more available, it is a special effect image in which all details of the exposition are saved in a specific format and clearly visible as light and dark colors. For example, You decide to photograph a panorama or landscape in the evening or early morning. In the first case, with the standard settings of the camera you will get dark photos, and to highlight clearly the dynamic range of the image is not possible. The same applies to the second case, dawn will be very difficult in terms of technical design stage, because the bright rays of the sun blocking out all other parts of the image. So, what about then? This is what we will discuss today.
HDR - High Dynamic Range Imaging
High Dynamic Range (extended dynamic range) helps with maximum precision to fit the image to this option, which we see in reality with the human eye. He (the eye), of course, sees in fact the small number of parts in light and in shadows at the same time, but the adaptation of the pupil to the existing lighting conditions, the sensitivity increases several times.

In order to obtain HDR images?
First, if you are using an SLR camera, you will need a special setting for shooting several frames per second. The exposure step should be changed to some stairs up and down. The figure below presents the images photographed with the use of this technology, and changing “Exposure Value” or “exposure”. Next is a comparison of an ordinary photo and HDR photo.

If you use a mobile phone (iPhone or Samsung etc), then there may be the option for shooting HDR images. But make no mistake because this is just the final effect, as mobile devices still have not yet learned “on the fly” to take pictures in that format. Therefore, in order to make a real HDR photo, you’ll need at least a few high-quality images.

Processing HDR photos
To properly edit these photos, you’ll need specialized software. Often use either Photoshop, or Adobe Photoshop Lightroom. I personally use Photoshop CC, in fact it is possible to get everything.
Also very important point when receiving the HDR file is the output format of the image, so I recommend to shoot initially in RAW format to the image processing takes a minimum time.

Insights
If you need to highlight the details of the image from dark shadows to light highlights, then take photos using RAW format. Then edit it in Photoshop or any other graphic counterpart. Use the HDR effect is neat, because not always it looks natural and not all images need this treatment.
