Perfect Layers (Home) 25
Navigator, Loupe, Histogram and Info At the top of the control panel on the right of the main window is the Navigator | Loupe | Histogram | Info panes. It contains four useful tools for inspecting and viewing details of your image.
The Navigator Pane This gives you a birds-eye view of your image. The blue square region marks the image area that is visible in the preview pane. You can pan your image by clicking and dragging inside the blue region. At the bottom of the Navigator pane are several Zoom presets. Click on a Zoom preset to activate. FIT: Zooms to fit the current canvas size. This allows you to see your entire image. FILL: Zooms to fit the current layer. This is great if you are working on a layout and want to zoom in on a smaller layer you are adjusting. 100: Zooms to 100% or actual pixels. This is best for judging small details. 50: Zooms to 50% 25: Zooms to 25%
The Loupe Pane This gives you a magnified view of the section of the preview under the cursor. This allows you to view the quality of your results while maintaining a complete view of your image. At the bottom of the Loupe Pane is a sliding for adjusting the zoom level.
The Histogram Pane This gives you a color chart of the shadow, mid-tone and highlight areas based on the image RGB values. This is useful to show areas within the image that may be clipping. Clipping is when your image contains pure blacks or white and can signify loss of highlight or shadow detail. The left side of the histogram represents the shadows, while the right represents the highlights. At the top of each end is a triangle. If the triangle is lit, there is clipping on that side of the histogram. If you click on the arrows, you will activate the clipping overlay on your image. The areas of your image with a blue overlay are pure black, while the areas with the red overlay are pure white. You can turn the clipping view off again by clicking on one of the triangles. You can also temporarily enable clipping view by holding down the J key at any time. The clipping view is useful when you are making adjusts to the brightness and contrast of your image. The Histogram pane also displays the RGB values under the cursor at the bottom of the pane.
