To make your selection, click one corner of the
rectangle that will be your selection, then drag
your mouse to the diagonal corner and release it.
You can resize your selection by dragging its
edges, and you can move it by clicking in the
middle of it and dragging it to where you want it.
After you have selected a zone, remove the red by
clicking the Red-eye icon beneath the photo.
Access this function by clicking Edit > Sharpen.
Adjust the values for Amount, Radius, and

Choose the central point of the area you want to

the photo. Adjust the amount of blurring, then click
Apply.
