Open multiple windows of the same image

In Full Edit, you can open multiple windows to display different views of the same file. A list of open windows appears in the Window menu, and thumbnails of each open image appear in the Photo Bin. Available memory may limit the number of windows per image.

 Choose View > New Window For [image filename]. Depending on the position of the first window, you may have to move the second window to view both simultaneously.
You can use the New Window command when you’re working with a zoomed image to see what the image will look like at 100% size in a separate window.
