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 • Take 3 – 7 exposures at different Ev • Load exposures into HDR Program (file conversion may be necessary) • Run HDR creation step (Generates 32 bit image) • Run Tone Mapping step (Reduces image to 16 bit) • 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
