HDR Crash Course (Part 1)
HDR or high dynamic range is simply an image that has very high dynamic range from darks to lights. When you take a photograph your camera does its best to capture the full range of colours but alas cameras are not as good as the human eye and can only capture a certain range.
For example if you take a picture on a nice sunny day you may find that the sky is a wash of white. Instead the sky should have been filled with clouds. The same goes for the darker colours. (Of-course this also depends on what your camera has be set to, or focused on) The point is cameras can only capture a certain amount of the colour range(from Dark to Light).

HDR is the process of taking multiple images at different exposures and then combining them to create an image that has a “High Dynamic Range”. In other words creating an image that has more accurate & sharper blacks and whites, without compromise. To create an HDR image, you would take at least 1 x underexposed image (black image), 1 x normally exposed image(as the image should be) and at least 1 x overexposed image(white image).
You would then combined the 3 or more photographs in HDR software like “Photoshop’s HDR Pro” or “Photomatix“. Hopefully the end result is an image that has a lot of extra colour and details.
