About HDR Effects  Renders the scene as the photographer saw it  Captures large range of exposure values (Ev)  Captures highlight detail in underexposed images  Captures shadow detail in overexposed images  Controls noise in shadows  Final images have wonderful color & infinite detail

General HDR Process Steps 1.Take 3 – 7 exposures at different Ev 2.Load exposures into HDR Program (file conversion may be necessary) 3.Run HDR creation step (Generates 32 bit image) 4.Run Tone Mapping step (Reduces image to 16 bit) 5.Post process image for tones, saturation, etc

Camera Set Up Camera on sturdy tripod with cable release Set camera program to Aperture Priority Turn off automatic settings such has White Balance, Autofocus, flash and ISO Set ISO to low value to reduce noise Use Manual focus Continuous shooting mode Raw 12 bit files

HDR Shooting Compose and shoot one image as normal Then shoot 1 image at – 2 Ev Then shoot 1 image at + 2 Ev Or if available, use camera’s Automatic Exposure Bracketing (AEB) to shoot 3 rapid exposures (Canon) On certain Nikon models, shoot 5 – 7 AEB exposures at 1 EV increments each

Tone mapping is complicated. Photoshop CS3 / CS4 Works fine with middle to low contrast scenes. High contrast scenes difficult. May create artifacts.
