Master high dynamic range imaging to enhance tonal range or create hyperrealistic effects
10. The Hue/Saturation adjustment is one of the functions that works in 32-bit space. Photo Filter, Channel Mixer and Levels are a few more. Here, we’ll boost the overall Saturation of the HDR image, so there’s more color-contrast “pop” after tone mapping.
11. Next, we repeat the bit-drop routine to launch HDR Conversion and re-load our saved settings.
12. We have to do some minor adjustments to account for the saturation boost, but we’re much closer than we would have been had we skipped that earlier step. Click OK, and the HDR image is tone-mapped into 16-bit/channel space.

• A tripod ensures alignment between each captured frame.
• Change the shutter speed to vary exposure—not ISO or aperture (use aperture-priority
• RAW shots work best, but JPEGs also can be used.
