Another option is to use an online service which improves image quality. RetroReveal is relatively easy to use and is free. I've used it and i'm certainly no computerphile.  The site is: http://retroreveal.org/upload
Also, MyHeritage has a service to improve images. It is free for up to 5 images, even if you're not a Premium member.
