Use the Adjust dialog when you want complete control over image corrections. Use the tabs on the Adjust dialog to adjust the brightness and contrast, flash and backlighting, color balance, saturation, and sharpness of an image.
Each tab on the Adjust dialog contains slide controls and a preview window. The preview window splits the original image in half, and shows the original image on the left, and the new (corrected) image on the right. To view more or less of the new image, click and drag on the arrow at the bottom of the preview window to the right or to the left.
To use the slide controls, simply click and drag the arrow to the left or to the right. If your mouse has a mouse wheel, you can also use it to adjust the slider.
To change the magnification of the image in the preview window move the mouse cursor over the preview image to change the cursor to a “magnifying glass” icon. Left-click the mouse button to zoom-in (magnify) the image. Right-click the mouse to zoom-out (reduce the magnification of) the image.
