These controls let you adjust the method of tone compression used, affecting the overall look and strength of your HDR effect.
Here, you can make essential adjustments to exposure and contrast, and recover details in the highlights and shadows of the image.
Applying HDR effects not only impacts image exposure, but also can cause shifts in color temperature and saturation. These controls let you fine-tune color, from completely natural to totally wild.
Like all Nik plug-ins, HDR Efex Pro 2 has U Point technology Control Points that make it easy to confine an effect to a specific area of the shot. Drop a Control Point onto the image, and you can adjust exposure, contrast, saturation and structure selectively without complicated masking.
The Finishing Panel has tools to create a vignette, adjust levels and curves, or simulate the effect of a graduated neutral-density filter—subtle refinements to put the finishing touch on your image.
LOUPE & HISTOGRAM
This panel, when expanded, lets you switch between a magnification loupe and a histogram of your image.
