In photoshop CS4, how do you make the picture unfuzzy?

Clear images are the function of the camera, not editing. Stabilizing the camera on a tripod to prevent camera shake in low light situations would cure your problems, not Photoshop.

I'm not saying htis to be mean but you should learn how to take proper pictures instead of relying on photoshop to save your pictures ... it;s not like on TV shows where the CSI team can zoom into an image to infinity and the program can create detail out of one black pixel ... post processing can only go so far and even cutting edge features that are still in development can;t even come close to doing what they do on these cop shows. Adobe IS working on an unblur tool but even they admit that the end result is garbage for anything other than forensics (trying to unblur text taken with a shacky camera for example). Their new algorythm (not out in any version of photoshop yet ... still in the lab) help reduce blur but creates alot of ghosting and artefacting. You can try to use the shrpen and un-sharpen mask filters but don't expect amazing results from this ... garbage in = garbage out.

Filter->Noise->Reduce Noise That will help, but it won't make the "fuzz" go away, just reduce it a little. You under-exposed it in the first place, which decreases the signal to noise ratio, and makes noise very visible. The only way to "fix" that completely is to not underexpose in the first place. Peace

"fuzzy"??? you mean camera shake through not knowing how to use the camera properly??? you can't in photoshop...

before use of photoshop, you want to make sure camera is set on best quality available, and jpg is good, raw is better, you do also want to have good lighting in room or area, so camera can pick us shaded details, if setting for image is lower that high quality, and setting is not correct for dark or night shots, details in image may appear pixeled, noise, or low gamut, and possibly not ecoverable, if it is noise, you can try denoise tools, Topaz DeNoise http://www.topazlabs.com/denoise/ Ximagic Denoiser http://www.ximagic.com/d_index.html if it is pixeled, you can try sharpen unsharp mask tools, Perfect Resize 7 http://www.ononesoftware.com/products/perfect-resize/ Focusmagic Sharpen Your Blurred http://www.focusmagic.com/ if it is gamut, that would mean image is all black (red) only in areas, and not adjustable, COLORFLOW - Kodak http://graphics.kodak.com/US/en/product/value_in_print/colorflowsoftware/default.htm Prove It!,Win http://www.publishingperfection.com/colorblind/cob110/ ..
