Since 1999, SkyscraperPage.com's forum has been one of the most active skyscraper enthusiast communities on the web. The global membership discusses development news and construction activity on projects from around the world, alongside discussions on urban design, architecture, transportation and many other topics. SkyscraperPage.com also features unique skyscraper diagrams, a database of construction activity, and publishes popular skyscraper posters.
Being the bonehead I am I wasn't sure what HDR is so I Googled. Here is a pretty good explanation (I think).
High dynamic range imaging
From Wikipedia, the free encyclopedia
In image processing, computer graphics, and photography, high dynamic range imaging (HDRI or just HDR) is a set of techniques that allows a greater dynamic range of luminances between light and dark areas of a scene than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows.
High dynamic range imaging was originally developed in the 1930s and 1940s by Charles Wyckoff. Wyckoff's detailed pictures of nuclear explosions appeared on the cover of Life magazine in the mid 1940s. The process of tone mapping together with bracketed exposures of normal digital images, giving the end result a high, often exaggerated dynamic range, was first reported in 1993, and resulted in a mathematical theory of differently exposed pictures of the same subject matter that was published in 1995. In 1997 this technique of combining several differently exposed images to produce a single HDR image was presented to the computer graphics community by Paul Debevec.
This method was 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 this process. This composite technique is different from (and may be of lesser or greater quality than) the production of an image from a single exposure of a sensor that has a native high dynamic range. Tone mapping is also used to display HDR images on devices with a low native dynamic range, such as a computer screen.
"I had this job once where I had to attach things together with small pieces of metal. It was riveting."
I tried playing around with HDR a little bit. I know most people don't care for the over-stylized, fake-looking HDR, and I tried not to get too crazy with it, but I'm new to it, so cut me some slack.
All were created using a free program called qtpfsgui (catchy name, right? ). Larger versions are available on my flickr page if you click the photo (and then click "all sizes" on the flickr page). There are also a couple other HDR photos on there.
