Nik HDR Efex Pro

Easily create dramatic HDR images with the advantage of 32-bit color and multiple tone-mapping algorithms

This Article Features Photo Zoom

WORKSPACE CONTROLS
Here you can adjust the zoom level of your image preview and also select white, gray or black as the workspace background color. You also can toggle the control palette on and off for a larger, unobstructed view of your image.

PRESETS
Over 50 preset effects let you easily experiment with different looks, from realistic to wild. All of these presets can be fine-tuned with global adjustments and Control Points.

TONE COMPRESSION
This is the slider that controls the amount of tone compression—the main effect of HDR techniques.

GLOBAL ADJUSTMENTS
Here are sliders to let you fine-tune the included Presets or create your own. Changes you make here will be applied to the entire image.

FINISHING ADJUSTMENTS
With these options, you can add a Vignette to focus the viewer’s attention and also adjust the image’s Levels and Curves.

CONTROL POINTS
One of our favorite features of Nik Software apps are their Control Points, which make it easy to selectively adjust specific areas of an image without complex masking. Simply add a Control Point to the area you want to adjust, and use the sliders to adjust the radius of the effect, along with exposure, contrast, saturation, HDR method strength and all of the other adjustments available in the Global Adjustments palette. This allows really fine control over your finished image, as you can increase or decrease adjustments only where you need to.

CONTROL POINT PALETTE
Listed here are all of the Control Points you’ve placed on the image. The percentage value represents the size of a Control Point’s effect as a percentage of the total image size. You can uncheck any of the Control Points to see the image without the effects of that point. Clicking on the far-right check box gives you a black-and-white preview of the areas of the image affected by the Control Point similar to a mask preview in Photoshop.
