Light restoration is the minimalist of restorations. The amount of damage to repair on the photograph should be quite light and should be in low-detail areas of the photo. This also includes, blemish correction, red-eye, and eyeglass glare removal.
Medium restoration includes repair to small scratches or bends in non-detailed areas of photographs. This level also allows for the removal or addition of objects or people in photographs, as well as colorization of photos.
Extra-Heavy Restoration includes nearly full reconstruction of a photograph. This would include photos that have been ripped several times, or have holes in detailed areas such as faces. Includes colorization if desired.
