In order to make the perfect or professional HDR photos, we at least need a digital camera, a tripod and HDR software such as Photomax, Artisan, easyHDR, Dynamic Photo and many more. Certainly, several of these software pro are not free or need to be paid. The best alternative is by using the latest version of Photoshop that already provided the direct covert through the HDR pro tool. However, trying to create HDR photo online with the single photo can actually be quite easy. It can be tried by one of the HDR tools online at fotor.com.
The followings are the simple and easy example to create the HDR photo by using Photoshop and combianed with the free software "Luminace HDR". It can be downloaded first here.
Step 2: In the Photoshop Choose File - Automate - Merge to HDR Pro. Merge to HDR and then add the three photos that will be combined together. This works on Photoshop CS2 – CS6 (CS2 Doesn’t have auto align and it’s called “Merge to HDR on versions older than CS5).
The merged result is a floating-point 32 bit image. Neat, in the section of HDR pro box, we will be able to organize photos that have been uploaded earlier. There are 3 main parts in the dialog screen preview; the order of the photos and the part of image settings. In this example, the setting is being left at the default with the size of 32 bit images.
By choosing Default, we have acquired the realistic HDR photo. You can view the available tones by sliding the White Point slider to examine the range of tones, When it has been done, go and save the HDR image in the format of TIFF or OpenEXR (*.EXR).
Step 3: Run Luminance HDR that has been downloaded earlier and open the HDR photo from Photoshop on the menu Open HDR Image.
At the interface of Luminance software, there are several options such as tone mapping (Mantiuk, Fattal, Drago, Durand, Reinhard, Pattanaik and Asikhmin) that will be useful to map the photos into the different dynamic ranges. Just choose one available operator style and then click the button to Tonemap. In the example below, we use "Fattal" with the following setting:
For several visual view, every operator tonemap will be different. Each operator takes the input HDR image and processes it in its own way. Additionally, each operator has its own collection of parameters with sliders that allow you to further modify the actions of the tone mapping. We will be able to adjust it depending on the character of the HDR background.
