Take a High Dynamic Range picture every day for a week
You will need to post everyday a HDR picture in the challenge feed
To learn a new technique or improve an already known one.
High-dynamic-range is a technique used in photography to reproduce a greater dynamic range of luminosity than with normal digital imaging or photographic techniques. The aim is to present a similar range of luminance to that experienced through the human visual system. The human eye, through adaptation of the iris and other methods, adjusts constantly for the broad range of luminance present in the environment. The brain continuously interprets this information so that a viewer can see in a wide range of light conditions.
High-dynamic-range photographs are generally achieved by capturing multiple standard exposure images, often using exposure bracketing, and then later, merging them (usually within a photo manipulation program) into a single HDR image. Digital images are often encoded in a camera's raw image format, because 8 bit JPEG encoding doesn't offer a great enough range of values to allow fine transitions (and regarding HDR, later introduces undesirable effects due to lossy compression).
Any camera that allows manual exposure control can make images for HDR work, although one equipped with auto exposure bracketing (AEB) is far better suited. Images from film cameras are less suitable as they often must be digitized first, so that they can later be processed using software HDR methods.
We are pretty sure that you saw before a lot of HDR pictures, thinking that involve difficult post processing or Photoshop knowledge, this challenges will show you how easy is to create a HDR image and then you can use this technique in the future if you like.
It is always better to take at least 3 different pictures to make an HDR photo, one photo overexposed, one sub exposed and the last one with the normal right exposure, it is very easy to do this with the bracketing option present in almost every modern camera, or manually exposing for yourself. Use a tripod to take the pictures and do not move it until you take all the pictures. After you have all your pictures, import them in your favourite software like Photoshop of Photomatix and play with the parameters!
