Series of Images demonstrating the creation of High Dynamic Range Images

The top-left image is the result of processing the adjacent seven the RAW images taken with a NIKON D300 in 16-bit NEF-RAW format.
This is the first attempt to pass the creation of an HDR-Image fully to my newly created 'Remote-Shutter-Release-Timer' (RSRT) running on an ARDUINO.
As a first step I measured the given light conditions with a SEKONIC lightmeter. Both the highest and the lowest readings were entered into ARDUINO which then calculated the optimum range of exposure. Further, the number of images to be taken can be influenced on ARDUINO by indicating the EV steps (1/2, 1, 1 1/2, 2 Exposure Values aka as f-Stop). These values were entered into to the camera in the form of a baseshot exposure time, the bracketing steps and the bracketing width (number of images to be taken - max.9 with NIKON D300).
Finally after setting the focus, ARDUINO fired away instructing the camera to take the seven shots by triggering the shutter-release.
Back home with the aid of the 'digital lightroom' (pronounced computer) and a great peace of software named 'Picturenaut' the seven NEF RAW images were imported into Picutenaut without any modification.
For the process of compressing the linear High Dynamic Range Image-data (32-bit) into a viewable 'Low Dynamic Range Image' the 'adaptive logarithmic' algorythm and a Gamma of 1.2 were applied.
The result seen here shows a great degree of brilliance and high luminance that was achieved by the process described above. Attempts of 'photoshopping' any of the base images could barely reveal a similar image. As a final step the resulting image was sharpened and resized only in Photoshop.
