My Experiments with HDR

My first HDR images for you.

High Dynamic Range (HDR), as it is called, is a new technique in photography which can create outstanding images by merging multiple images of a photograph taken at different exposure settings. The resulting images reproduce a very high range of tonality and detail.
Generally while taking a picture with a very high range of lighting and illumination, it is extremely difficult to capture all the details as the highly illuminated highlights may get burnt out (washed out) due to over-exposure while the darker details of the shadows may remain under-exposed. So to get over this dilemma we can take the photograph with at least three different exposure settings to capture maximum illumination and lighting detail in three different images. These different images can then be merged with HDR software to create a resulting image reproducing maximum tonal range and detail.

The best thing about this technique is that we can create images closest to the resolution of the human eye in terms of response to light and may be even beyond. On the other side, with the liberties of creative expression of the modern day, one can take it to extremes and result in creations of very surreal and ‘ghostly’ images. Some artists also create images that have an interestingly peculiar painting-like effect.
