emvarona (via gimpusers.com) There are several ways of sharpening slightly 
blurred photos. The easiest is (1) Filter-enhance-sharpen.Another is (2) 
Filter-enhance-unsharp mask. Better still (found in Gimp 2.6) is (3) 
decompose/compose method. It requires a lenghty explanation. Instructions are 
found in the gimp on-line manual. There are other ways but even more 
complicated. I use all three above, however, the third one gives the best 
results.

Or maybe there's something wrong with the lens. I bought a little
Aiptek Pencam recently to use in places where I don't want to risk
a better camera (kayaking, hanging from model airplanes ...)
The center and lower right of the field is usually more or less
focused, but the left and upper left are always out of focus.
Apparently the lens is just installed poorly (I know these cameras
can take sharp images -- I've seen some). I hear it's possible
to disassemble the camera and fix the lens alignment, though I
haven't had time to try it yet. Of course, if this is your only
camera and you paid significant money for it you might be better
off trying a camera repair place.

ok, ok, i understood!

This person seems have to been a little bit TOO optimistical ;)

Well, as far as i am no professional in image-editing, i just believed it, as 
it is always shown on tv in some police-documentations where they get a clean 
picture out of some sort of webcam-picture ;)

So i'll have to try out the plugin and if that's not enough for me, it's my 
bad luck...

Thanks so far, Qeldroma

if this is the case, then any marketing corporation should be able to

Maybe he can unblur it for you?

I'd like to see any before/after comparisons for fixups of this type, PS
or gimp.

Image size or such does not mean you can't get focused, sharp pictures.
If every image is blurred, something is wrong with the camera or the user.

Did you try using a tripod, or resting the camera on table/beanbag/whatever?

Or turn on a bright(er) light?

No matter how, because EVERY image get's blured. It could be summer in the

It's just a 2MPix handy-cam, so that's the reason, but i don't need PERFECT 
results, just a little bit better results, i know i know, it's just a 
handy ;)
The lens is clean, though.

Good idea, sounds interesting! Will try it out, thanks

2005-11-01 Thread Tim E. Jedlicka - wrk
gimp wise you could try Filters->Unsharp Mask.

But as for the camera - I couldn't tell from the sample pic if it is a focus 
problem. Is it focusing someplace else - easier to tell if there is more depth 
in the photo. Take a snap of a brick wall from an angle, or snap a photo of 
some stairs.

Is it a dirty lens? Take it into your local camera shop and ask them to clean 
the lens for you (should be free).

If you have the f-stop and shutter speed of the photo that would also help.

2005-11-01 Thread Kirk Thibault
The image looks blurred by camera shake with the long shutter speed  
and a non-steady handheld photo.  unsharp masking probably won;t help.


Try going here:

http://registry.gimp.org/list?category=12

and looking at the plug-ins that "refocus" the blurry image.  I have  
not used these plug-ins, but they seem to be based on algorithms that  
detect the intent of the "focused" image and attempt to reconstruct  
it.  A bit more sophisticated sharpening.


Here:

http://refocus-it.sourceforge.net/

is an explanation of one of the refocusing plug-ins.

Good luck!

The advice about using a tripod or other steady surface is key.   
Another thing to consider is, if your camera has it, use a timer to  
release the shutter so you are not physically touching the camera  
when you open the shutter - this avoids camera shake as well.  Then  
you can open the shutter and can leave the shutter open for a while  
while maintaining a sharp image with no shake.

since i do not use Windows and as a linux user, i do not have enough
time to discover all of the excellent and well known software available
to me, much less to keep up with Windows software of the day -- i would
be interested in hearing the names of the "well known" utilities that
could handle such a photograph that are available to windows.

i am sure your willingness to answer will be just as keen as your
willingness to ask for help here.

How was the camera being held?  Was it sitting on something, or was it
in your hand?  If it was in your hand, try putting it on a stable
object (e.g. tripod, chair (risky, but sometimes it works)) or getting
a digital camera with auto-stabilization or whatever they call it
nowadays.

I would say, probably, no.  That said, try scaling it down using
linear or something, maybe that helps?  I doubt it, but maybe it's
worth a shot.  Generally, for something like this, the best thing
would be to get it right the first time, if possible.  Even if that
means taking the same picture 3 times just in case.
