Ship Wreck HDR
There is a wrecked ship lying in The Gurpur River near Tannir Bavi, Mangalore. Locals claim it was wrecked during the 2004 Indian Ocean earthquake and tsunami. It provided me a very nice opportunity to test the new version of Photomatix Pro 4 software. Even though Adobe Photoshop has now built in HDR function, Photomatix is one of my favorite HDR software.
High dynamic range imaging (HDRI or just HDR) is a set of techniques that allow a greater dynamic range of luminance between the lightest and darkest areas of an image than current standard digital imaging techniques or photographic methods. The human eye can perceive scenes with a very high dynamic contrast ratio, Human eye sees more than 15 stops with a contrast up to 16384:1. Adaptation is achieved in part through adjustments of the iris and slow chemical changes, which take some time (e.g. the delay in being able to see when switching from bright lighting to pitch darkness). At any given time, the eye’s static range is smaller, around 10,000:1. In contrast digital photographs, color negatives and slides consist of multiple film layers that respond to light differently. Most digital camera sensors have 11 stops of light with a contrast of 2048:1. To obtain High dynamic range we need to resort to High dynamic range imaging technique.
Ship Wreck HDR
I used my Canon EOS 5D mark II with Canon EF 16-35mm f/2.8 L USM Lens to take this photograph. I shot three bracketed shots with 2 stop exposure variation between the shots. So one shot was 2 stops under exposed than the normal exposure, second shot was correctly exposed and third was 2 stop over exposed. I fed these 3 shots into Photomatix through Adobe Lightroom using the new Adobe Lightroom plugin. After going through the Photomatix it produced a 32 Bit file which I did tone mapping to my taste. After developing in tone mapping process of Photomatix it was imported back to Lightroom as 16 bit Tif file. I exported the correct exposure file and the HDR file to Photoshop to remove the ghosting artifact. Once corrected I re-imported back to Lightroom.
Ship Wreck HDR
I would recommend any HDR enthusiast to refer to the invaluable HDR website along with very informative tutorials by Trey Ratcliff called Stuck In Customs. It has given me several insights, tips and methods to improve on my HDR photos.

Business as usual
Votrasi Imaging had organized a multi-city photo walk yesterday. I attended two places of this Photo walk. One was at Karkala around Anekere lake. Shiva Shankar and me went around exploring the waterbirds in and around Anekere.
Sleeping Boats
I had sold my Canon EOS 5Dmark II & Canon EOS 7D and purchased Canon EOS 1D Mark IV. This monster of a camera is top of the line Professional camera from canon stable. Learning curve was huge. We wanted to explore the 45 auto focus point capability in catching the bird in flight. I went with my trusted 300mm f/2.8 lens + 1.4x III extender. Shiva was equipped with his 500mm f/4 lens.
Sleeping Boats
Here are the result which is posted by Shiva on Flickr. Intermediate Egret & Purple heron.
Friends
As you can see the camera shined and was very quick in catching focus and keeping it in focus. I need to learn the millions of settings which control the auto-focus behavior of the is camera before writing a review.
Helm of affair
4:30PM evening I joined the photowalk group at Mangalore. We started at Sultan Battery area. We did a brief walk taking photos around the Gurpur river and later took a ferry ride to the sea side. When we finished at the beach front it was half an hour after sunset. We took the ferry ride back to the starting point.
Lead the boat
There I did a brief talk along with discussion about ‘Macro Photography’. It was a refreshing fun filled session with everybody doing something on their own including pranks on each other. I got to know many of the Votrasi gang who were really a great enthusiastic bunch of youngsters who are eager to learn. My session on macro photography seemed to have been absorbed intently as I could not see any yawn or lack of concentration from any of my audience even though it was fag end of the day 
.
Male Coral-tailed Cloudwing
I thoroughly enjoyed the great interaction and will be looking forward to more such events. You can check out my photos which are quite different from my usual photography.
