I agree with what has been said about the Photo Enhancing Apps, in my view, they are very artificial and make the images look as though they were taken yesterday, fine if your photo was taken in the 60s but not for historical images.
It would be a very sad day if a false, one click App were to replace the years of experience of the many true photo restorers who give their time on the board, not to mention the skill and talent required to achieve a good result.
Example: I spent two hours on this post restoring and colouring a photo only for it to be overlooked in preference of the ones that had been recreated using such and App. Needless to say, I removed was surplus to requirements.
