We can’t say for sure without seeing the photo first. The vast majority of photos can be restored, it depends whether the amount of damage means the cost will be too much for you. If key detail isn’t there – faces or eyes – and you don’t have another photo we can use to add those elements from then it’s unlikely your photo can be mended. If one eye is clear we can usually use that to recreate the other one – particularly if the subject is facing full on. If the photograph is faded so much you can’t make it out then it may be beyond recovery.
