Removing noise how ?

Hi,

Well I have this image here :


What I'd like to do is remove the noise/grain without blurring the image too much... Can anyone help me out ?

Thanks

This image is mostly damaged beyond repair. Your channels are a mess......the blue channel is almost unrecognizable, and the red/green contain enough noise that replacing the blue one is worthless. Also there's so much noise in the red/green channels that "without blurring too much" isnt an option.....and there's no real way to sharpen it back up.

Your choices are lower the saturation and resize the pic smaller (basically try to hide the fact that it's low quality) OR get another picture (if from a webcam, then try to add as much light around the subject as possible.....the more light the less noise)

Yeah, I'd say it's impossible to get a good result with this photo... or if it is, it's not very worth the time and effort.


You could try to turn it up in a black and white picture, then add a little bite of noise and play with the curves to adjust the contrast... you should come out with (at least) a better result then what you have right now, because the red/green pixels that show the low quality of the photo won't be visible...

Just a tip

Thanks a lot for the replies ppl !

Hmm just seems very weird that the pic turned out this way I mean it was taken with a 3 mega pixel cam... Oh well... guess it's gonna have to turn out black and white...

Duplicate the layer, run the Filter > Noise > Median filter with a level of about 2 or so. Then set the layer opacity to about 60% or so. Use a soft eraser and erase the eyes of the Median layer.

That's a quick fix that should work nicely. Colour correct as desired.

I have'nt checked the channels but if (as I presume they are) the channels are bad as others say, you could do a lot worse than convert a copy of the image to LAB space and replace the worst affected channels (blue and green normally contain the most bad data). Obviously this will mean drastic colour correcting afterwards.

Thanks a lot for all the help ppl !

I think Spectra's tip seems to be working best with this image (THANKS!), I'm gonna try working with the channels now.

THanks !
