High Dynamic Range


What is High Dynamic Range, also known as HDR, This is set of shot's taken of the same object or scene in five to three under exposed and over exposed images. When combined these five or three images it gives you a whole tonal range in one image. From the bright areas to the dark shadows. This sometimes gives you a surreal look to the image. Many good HDR images out there take time to create, meaning an HDR image can’t be taken right then and there. There is alotof steps involving to make one image look its best.

Others call this a waste of time, pointless and over processing photography. Personally I think this is just another type of photography we need to accept. Sure it’s over processing images, but sometimes it's worth it. One shot taken by the best camera can't capture the whole complete range of colors in one image.

Two top programs that can be used are Photoshop and Photomatix.
Here are three images that I have taken with the exposures of 1+ 0 -1
with these images taken in a raw format you can now send them into Photomatix. This is there the three or five images will be put together into one image.


After putting the three or five images together you can now do the tone mapping. Tone mapping controls the the colours how much light, contrast, range, ect


In the end after the final touches in Photoshop you have an hdr image!
Here are some more shots that I have taken with this use of photography.
