HDR Explained…Z-z-z-z-z…

HDR Image by Christian Bloch

Graphics.com has posted an excerpt from Christian Bloch’s book, The HDRI Handbook: High Dynamic Range Imaging for Photographers and CG Artists.

In the post, Christian explains in terms of digital bits how an image is captured by the camera compared to how our eyes perceive the image.

Then he goes on to explain what happens to an image from digital camera capture to display on screen, touching on gamma encoding along the way.

And finally, he shows us how an HDR image is cobbled together from multiple shots of the same scene, resulting in a much improved image.

In all, a very useful and interesting dissertation to make one understand High Dynamic Range (HDR) imaging, if you really have to get down and dirty with it. For many people, it is most educational; for others – me included – it’s a sure way to meet Wynken, Blynken and Nod.
