Hello,
A week ago, I got married. Today we gathered all the photos taken that day.
However, several photos are blurry...
I would like to know if there is an existing way (a software, an option... or anything else :) )
to recover some sharpness from these pictures.
Thank you in advance!

Myth:
With computer processing, you can unblur a photo, that is, obtain a clear photo from a blurry photo.
Reality: FALSE.
Explanations: The computer cannot invent the details of the image lost due to blurriness. To make an analogy, it's like wanting to get eggs, flour, and sugar from a baked cake: it's impossible!
The details lost due to blurriness cannot be recovered. Existing techniques can improve the visual quality of an image (sharpening edges, enhancing contrast, noise reduction, etc.) but in no way can they reconstruct what is missing. By interpolation, the computer can average certain pixels, but this will only add blur to the blur.
Computers that obtain a clear photo from a blurry photo only exist in movies.

on Photoshop CS5 and all the others
the filter/sharpen/unsharp mask function allows you to make an image sharper
it doesn't invent anything but reinforces the outlines of what is blurry with 3 settings and in the end, you really have a sharper image
no need to watch movies
If you can't see anything at the beginning, you won't see more after Photoshop
