My Grandad was in the Royal Navy in WWII, in the submarines. I went over to set up his new PC that I'd made for him a few weeks ago and he showed me a photo that a relative had emailed him, of him in his uniform back when he was about 20. The photo was in a bad state and I said I'd see what I could do to sort out some of the cracks, so emailed it to myself to see what could be done.
The people on there were amazing and I ended up with some brilliant results, so I printed them off and framed my favourite one to give to him. My girlfriend kindly recorded it for me, so that I could share his reaction with the people who helped make it happen!
