Franzis sharpening - making blurry images sharp?

1 year 1 month ago #625713 by Howard Swanson
Can this really work better than sharpening tools in Photoshop or Lightroom?  On their home page they have some convincing examples, but just wondering how accurate this is?

No BS… Really? Wow!

Let's be clear:

Sharp captures may be sharpened further by increasing
the micro contrast — tweak I never perform. This kind of
sharpening will produce way less artefacts (helloing)when
used in moderation.

The convincing examples you refer to are out of this world
and reality. No software can generate what does not exist.
It may, however, subtly accentuate — and in a very benefi-
cial manner — already existing information in a file.

Light is free… capturing it is not!

Yeah, I was not 100% sure what to think about this.  They have a free trial, I might download just to see what it can do.  :silly:

All of this un-blurrification stuff is a bunch of crap. Examples are contrived, whereas real world work is complex.

The best you can do is to try to mitigate blur on important parts of an image (eyes, e.g.) to help bring attention to them (and "overlook" other parts of an image). But basically, blur is blur, and any attempt to "fix" it never goes well.

Or perhaps I have not the skills.

What?  

So what happens when you have darker colors that blend together in a sharp world.  I don't see how this could be 100%.

I'll likely try this out as well.  Kind of curious now.  

LOL

No, I can't see this working and being all that effective.  Sorry.

Both of you are, in my view, correct.

That would only achieve visual confusion as parts known
to be at the same focal distance wouldn't be sharp.

You bring up a good point, how would this software detect if legit, the photographers intent to intentionally shoot at f/2.8 or f/5.6 for example to have the background blurred.  


Hmmmmmm

Again, one of those moments you say

Are you saying that sharpening options in post-procession are unable to sharpen blurry photos?

You can sharpen whatever you want, a blurry object, an already sharp object et.etc...But at the end of the day, it was a blurry object to begin with. A great photo begins with a well executed shot in camera photo....The rest is up to you. This site has everything from "documentary" style, merely recreating what it actually looked like for real, to fine art style photographers. Photography is ART, you can blur whatever you want......Its in the eye of the beholder.

A big difference between sharp and blurred details in a
picture is in the surface these details occupy in the shot.
Sharp details are many on a few pixels as blurred one will
"grow" in a halo form, lose their shape and contrast.

To sharpen blurred details, a software would have to re-
cognise the nature of the subject, its position in the field
of view and its details contrast. The picture is blurred be-
cause all these critical parameters have grown to such a
point that the software can only speculate them creating
the nastiest artefacts — most horribly noticeable in areas
with fewer tones.
