That depends on the condition of your original image.

"We can enhance faded and darkened pictures, repair tears and cracks, sharpen and brighten poor quality originals, reconstruct missing details, correct color from fading color prints."

We cannot restore pictures that are completely out of focus because too much detail has already been lost in the photo.

Reconstruction of missing areas can, under certain circumstances, be reconstructed.

A copy of an original photo can be restored to a certain extent depending on the original image quality, the better the original image, the better the restoration will appear.
