High Dynamic Range Imaging a.k.a HDRI. This is one of the interesting parts of editing your photo. For those who own a DSLR camera this might be useful for you. HDRI is actually technique combination between computer graphics and photography. The purpose of HDRI is to show the wide range of intensity levels found in real scenes ranging from direct sunlight to shadow ( range value between light and dark areas).
I’m going to show you some simple steps to give you the idea of HDRI. And to differencing the different exposure picture merge into HDRI before and after for you to compare.
Here are the set of 3 original different exposure picture taken from my friend Sony Alpha 200 DSLR camera (Thanks to Thoh).
First you need Photoshop CS. The one I’m currently using is CS3 version.
Step 1
Go to File > Automate > Merge HDR
Step 2
Click Browse and select the pictures then press OK
Step 3
Adjust the white according your preferable and set to 8 bits. (This is to save it as JPEG format later)
Step 4
Done! You now can save the picture any format you want or start edit the photo with other effect.
This is the simple example what I did add with some effect.
Try this with your photo and see how it looks like.
