My thanks and congrats to ipernity! The new sharpening algorithm is out.

Monday May 19, 2008 at 04:07PM

Recently I complained about over-sharpening of photos, which I found might spoil finer nuances. I asked ipernity if they were aware of the fact and if so, if they were planning to do something about it. I got a swift reply they were working on a fix.

 

Just some minutes ago I got a mail from ipernity that the fix was released and if I would like the new algorithm? Well, my answer is YES I LIKE THE NEW ALGORITHM! Thank you very much!

 

 

Just as a comparison between the old and new version

old

zigzag

new

zigzag test

 

 

 

old

Tree No 1030092

new

Tree No 1030092 test

Click on the pictures and switch to the largest version to see the differences best. Especially the old version of the tree photo suffers from a rather intense halo glowing.

 

Yup I like the new algorithm much, much better, thanks :-) Keep up the great work!

Best regards Alan

They always try to find out the best for us, that's one of the reasons I like Ipernity

Großartig. Mir ist das zwar nie aufgefallen, aber deine Vergleichsbilder beruhigen mich jetzt dennoch :)

Haha ja vandaar de stijgende kijkcijfers :-)

And a small correction not 'announced it a couple of days ago' but this afternoon

Ahhh now I know why one of my newer thumbs appeared unsharp to me because I was used to sharp thumbs. That's really a big difference. But it's ok I think. After all it's a thumbnail anyway and the full picture isn't affected by this I think.

Alan replies:
Well, I don't think, that anything is "softened"! What was changed, was that additional sharpening has been reduced, which could cause a halo glowing under certain conditions. Originals were never changed, sharpening, which actually is adding contrast on edges in technical terms, will still be applied on any copy I guess, just less aggressive.

But as you can see in my examples the new algorithm is much closer to the intention of the original than the old, especially the tree example shows nicely that oversharpening could spoil a photo completely. While post-processing on a website makes sense with photos that weren't post-processed at all, I don't think it makes too much sense on a site like ipernity where most people spend considerable time in post-processing to achieve a certain effect.

Besides that I do think that too much sharpening is a misguided perception which came up with digital photography, quite some people seem to believe that adding contrast, saturation and sharpness are the basic ingredients of a good picture. Well ....

Actually before the change I used to make different versions of my pics depending on where I uploaded them. For ipernity I switched on halo control which I usually don't need to use on my photos, just to balance the aggressive sharpening of the old algorithm.

I agree with you and the pictures demonstrate the effect very well!!

i don't think think too much sharpening is a misguided perception per se. there are pictures that "work" best with lots of sharpness, others don't. the art is in finding out where to sharpen the hell out of your post processor and where not. the same goes for saturation, contrast, brightness... well, anything, basically. ;-)

that said: yes, i know there are lots of examples with too much sharpening, but i might add that usually sharpening is only part of the problem there. take a look at this and cry: www.modellbahnboerse.org/rocokran2/IMG_2467.jpg

(the site www.modellbahnboerse.org is acutally a very good resource for lots and lots and lots and lots and - guess what? - even more lots of pictures in a very unique style. i tried to copy the style once but didn't succeed.)

i couldn't care less what thumbnails look like on ipernity, but your examples are a bit larger than thumbnails, so quality is an issue. the new version is much better, no doubt about that.

Well, if too much of ... whatever ... isn't a misguided concept, I probably can't help you ...

Actually we're talking about the same thing, I guess. See here: www.ipernity.com/blog/pedjap/66532
