7. Maximize the image window, by clicking its button
*Make sure you are clicking the mage window gadget and not the window gadget for the program itself.

8. Now the image view fills all the workarea, however we can't see the entire image, because it is too large. Another way to navigate large or magnified images is the Hand Tool. Activate it by clicking the button on the Toolbox

9. Drag the image to bring the hidden areas into the view
Note that you move the view only and not the image itself.

10. On the Options bar, click the "Fit On Screen" button*. The image view is resized to fit your workarea

11. On the Options bar, click the "Actual Pixels" button* to view image as it actually is with 100% zoom

*These buttons are available only while Hand or Zoom tool being selected. At any other time you can access Fit On Screen command using [Ctrl+0] (Zero) keyboard shortcut; to choose Actual Pixels view, press [Ctrl+Alt+0]

NB Always estimate the sharpness of an image at 100% zoom.
