:: H D R ::

HDR Images (High Dynamic Range Images) were originally developed for use with purely computer-generated images. Later, methods were developed to produce a high dynamic range image from a set of photographs taken with a range of exposures. With the rising popularity of digital cameras and easy-to-use desktop software, the term "HDR" is now popularly used to refer to the process of tone mapping together with bracketed exposures of normal digital images, giving the end result a high, often exaggerated dynamic range. This composite technique is different from, and generally of lower quality than, the production of an image from a single exposure of a sensor that has a native high dynamic range.

Though i have shot a lot of bracketed images quite a long time back, have not processed them then. Recently, got an opportunity to process my first ever HDR, after the trip to Bekal Fort Beach.

Processing HDRs is actually as simple as 1...2...3 points...
1. Open 3 bracketed images in PSCS2 / PSCS3 / Photomatix.
2. Merge them after aligning
3. Tone mapping and save as JPEG.

My first image here.....

I'm not sure about more HDRs coming from my NIKON TOY.
Comments and Critics... expected as usual..
