Restoring bad pics...

The whole image is 1,4 MB, it's a pic from Flickr, a painting from de
Heem;

This is what it should look like.

Next i will buy the DVD with all that stuff, but i was trying to make
it watchable...

1) Use of the perspective tool, cropping...

2) Applying some gaussian blur, then the smart sharpening script. On
the sample, because else it takes too much time.

3) adding some contrast, remove yellow (all less than 10%)

Anyway it seems that i can't get it sharp and nice....

So i wonder if all that tools we have can really make a bad photo
looking good, since the sharpening tools always create artefacts. Or
maybe i should do it manually, not using a script...

I tried to create a very clean mask by first applying a slight blur
before doing the edge detection...the major inconvenient of this
technique is that logically sometime, as of the border of the coup,
one create 2 edges instead of one...

Another nice effect !

Like here :

The amazing Grain Extract (Grain Merge is cool too).

http://www.gimptalk.com/forum/making-a-hollywood-movie-style-planet-t26639.html-view=next

These two layer properties are very powerful and I use them quite
often for a variety of things. This is one of the gems that GIMP has
and that PS has no answer for. The tutorial I'm about to show is the
amplication effect using Grain Extract; I'll start another thread of
some other cool Grain Extract tricks. I'll use ACE (Adaptive Contrast
Enhancement) filter for the tutorial (but any effect can be amplified
using this technique).

First get a picture to test. I chose this image from the free photo
index.

First Open the image and dup it for a total of three images. Then run
the GIMP ACE filter (note preview will be distorted for any layer ACE
is running on except Base layer, so keep that in mind) on the Center
layer and set the Top layer to Grain Extract and merge down. Now set
the result layer to Grain Merge and dup til happy (the more you dup
this layer, the more amplication you get. Below is the result of just
two dups using all default settings for ACE:

Interesting video this week on
http://meetthegimp.org/

A sharpening procedure called "octave sharpening"

A very quick first trial, still a lot of noise however.

Oh yes, i think if the photo is too blurred, there is no way. Even an
enlarged small image looks better than my original.

As i say. The only good thing is greycstoration, not too much effect
and smart effect.

Yes, Greycstoration, which I prefer and its successor G'mic are good.

Another is the excellent "wavelet denoise"
http://registry.gimp.org/node/4235

What I find is an endless loop
1. denoise and it makes the image soft.
2. Sharpen the image and the noise is back.
3. denoise and it makes the image soft.

I will try it, thanks.

I found also it's better to apply a filter through a bend (gradient)
mask, because the image is mostly blurred to the left, less to the
right;

i was wondering how to  clone large parts ? the biggest brush is
19x19 , circle ? i have installed so many brushes;..

http://www.flickr.com/photos/havala/4080548983/sizes/l/

with the 19x19 circle it's not easy to remove the reflect on the
left... i'm kind of fascinated by this painting :)

If you watch the wine grape you see the amazing amount of details De
Heem put into each grain...
