After "Next: Finish", you may wish to apply a few optional finishing touches, before saving. You can choose whether to automatically display the Finishing Touch window, using the check box at the bottom of the window. When not automatically displayed, the Finishing Touch window can be opened from the Utilities Menu.
Contrast and Sharpen
The Contrast and Sharpen tabs of the Finishing Touch window provide "Mild", "Medium" and "Strong" presets (and "Extreme" as well, for Contrast). The "Show Options" button gives access to options for more precise custom settings.
Crop and Straighten
The Crop tool allows you to click and drag on your image, to set a custom crop. The Aspect Ratio menu allows you to constrain your crop to standard aspect ratios, such as square, 3:4, 9:16, etc.
The Straighten tool allows you to correct a non-level horizon line, and correct vertical lines that are not quite vertical, such as in an architectural shot. Vertical Perspective has the effect of "tilting" the image slightly forward or back. The Rotation control allows you to adjust/correct the horizon line of an image.

Add Watermark
After processing your image, you can add a text-based watermark to it. This option is available for 8-bit and 16-bit images. The Add Watermark... option can be found under the Utilities Menu.
