It's blurred, no sharpening can fix that. AFAIK, there are no good methods to fix blurring, short of a tripod :-(

This is a good example of what i mean.

Filters-->Enhance-->Unsharp Mask gives better results.

Or ditching that case...that thing vibrates the space-time continuum.

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.

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.

touchette ...

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.

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.

Of course ;)

I have asked a designer someone from a marketing corporate and he told me, that this is no big problem with photoshop, but i can't speak of my own experiences, though..

Maybe he can unblur it for you?

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

How was the camera being held? Was it sitting on something, or was it in your hand?

No matter how, because EVERY image get's blured. It could be summer in the desert and it would get blured ;)

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 ;)

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?

ah, that is interesting. my photoshop using friend used photoshops limitations in this respect to justify upgrading her camera.

if this is the case, then any marketing corporation should be able to downgrade the equipment that their staff uses since it they purchased such a strong piece of software.

now i need to dig out my email addresses of all of the stock holders of all the big marketing corporations....

The lens is clean, though.

Every image?! Perhaps you have the camera set to "soft-focus" - sometimes suggested for taking romanticized portrait photos. Have you checked this setting?

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.
