Interface Controls


1 View Modes

Single Image View: In this view, the image is displayed with the noise reduction effect applied across the Image Preview area.
Split View: The image is displayed with a red line running either vertically or horizontally through it.
Side-by-side View: In this view, two separate previews appear. The previews are linked for zooming and panning. This lets you see the before- and after-images as a whole, or at the fine detail level.

2 Preview
The preview Function enables you to toggle on and off a preview of noise reduction effects applied to the active image. Check the Preview checkbox to display the effects, and uncheck the box to hide them.

3 Select
The Select Tool lets you select and interact with either Measurement Rectangles that you add to your image during the measuring process or Control Points that are added during the noise reduction process.

4 Zoom
The Zoom Tool lets you zoom in and out of your image. After selecting the tool, click on the area of the image within the interface that you want to zoom in to.

5 Pan
The Pan Tool lets you reposition your image while zoomed into the 100% or 300% views.

6 Background Selector
The Background Selector Tool lets you toggle the background color between Light Gray, Middle Gray, and Dark Gray.



7 Preview Modes
The Preview Modes enable you to observe the effects of noise reduction on individual elements of the image. You can display individual color channels or examine the masks created by different noise reduction methods. The Preview Modes are useful in judging the correct amount of noise reduction to apply.
