Old photo very blurry

[LibD]

My mother in law has given me a photo of her late father to try and retouch/unblurr for her.

It is very blurry I have tried smoothing but that didn't seem to do anything

I haven'tscanned the photo yet but took a quick picture on my phone to see if any apps helped...but to no avail just made it worse

Any help would be great as I have only just started using photoshop so I'm really new to this

Thank you for your help

This is a screenshot of the photo as I'm not sure how to save it from the photoshop app?

Blurry photos without details is one of the problems which technology is still not able to solve. You can try something with contrast or sharpening but you won't get details. Take a look at newest Topaz plugins which are promissing lots of things based on their AI technology. If half of what they are promising is true you will get something worth to spend time because you can use free trials for a month without paying anything for fully functional software.

As Bojan mentions it is difficult to provide more from less, and the newest non-Adobe methods do promise a lot better results, but honestly, my testing has not shown better results than those tools built into photoshop.  

Taking a look at your screenshot, and making an attempt at sharpening an image one generation away from an original, it was still possible to add sharpness to bring out details using just the Adobe tools.   Here's the results I came up with:

 sharpened a bit from a screen shot 

So I suspect you can do better with a soft original image.   

To reproduce this just copy the image layer.  Change the blend mode to overlay and use the median filter to apply some sharpness.  Don't go crazy, just a bit, flatten the image,  and do it again, lather rinse and repeat until your image has the sharpness you want.

I Hope this is the best
