what it called HDR photo


HDR or High Dynamic Range understood as a state or process of making images that contain a large range of dynamic rangethe range of difference between a "light" and the "dark" is very largecalled the dynamic range of exposureHDR was formerly called HDRI (High Dynamic Range Imaging).

Definition HDR as a "process", some say less precisebut it was already popular on the forums so yes we are wearing.

Others say that HDR is a technique of digital non-destructive if the purpose of making a digital image file of a photo eksposurenyya berobjek same but different values ​​so that it has a dynamic range of areas of higher than normal digital images produced from digital camerasThe ultimate goal of making HDR file is processing to display a unique pattern on the object image.


Three Main Steps How to Create HDR photos:

AMulti-Exposure
2Merge
3Tone-Map

In summary is as follows:
-Multi-Exposure: Make some of the same photo but different exposure(Bracketing).
-Merge: Combine pictures with HDR Merge.
-Tone-Map: Map to Perform Tone Tone combined to set the darkness bright.

It was the three main steps to HDRwhich is described in more detailEach time you want to create HDR imageseasy to remember there are three main steps in the process of HDR in the
"Multi-Exposure" / "Merge/ "Tone-Map"

So if there is a state of nature or portraits or anything in this world that contains a light and dark differences are very large (of the Dynamic Range) you can create HDR photos of the situation. Not always be daytimenighttime is also a lot that contains HDR circumstances.
