CN Tower – HDR

Filed under: Architecture, Documentary, Hand of Man, Night, Travel — collin orthner @ 3:45 am

An HDR (High Dynamic Range) image made with three images. One exposed for highlight, one for midtones and one for shadows. These were then combined in Photoshop to make one image that appears as I saw it. Most if not all cameras have a drastically reduced dynamic range( difference between pure black and pure white) compared with human vision. We can see detail into the darkest shadows and into some very bright highlights whereas the camera blocks up the shadows and blows out the highlights. I have to be very careful using this procedure as it can be easily overdone leaving me with a very flat, low contrast image or one that looks completey false compared to reality.
