Magnify photos using the Loupe
You can magnify a portion of a photo by placing the Centered Loupe over it. You can also leave
the Loupe stationary and set it to magnify the portion of the photo at the position of the pointer.
Using the pointer to magnify the photo is useful when you don’t want the Loupe to cover part of
the photo.

You can change the size of the Loupe and increase or decrease its magnification level. You can
also have the Loupe display a photo as a grid that shows the actual pixel composition of the
photo, allowing you to see the individual pixel values at high magnification (400 percent or
higher). You can also set the Loupe to display readings of the color values of a photo, showing
the RGB (%), RGB (8-bit), Lab, CMYK, HSB, or HSL values chosen for the Color meter.
