Depending on the intensity of the grain you could try the Median and Despeckle filters in the Filters/Noise menu, both are included in Photoshop by default.

That's probably the simplest way to go about it, but don't expect any miracles... ;)

To be honest you may be screwed. I use photoshop a lot and if the starting image is of poor quality it will stay a poor quality image. Your starting point is everything. The old syaing goes, "you can't make a silk purse out of a sows ear".

If the grain is bad after despeckle, dust and scratches and the like, the other option is a slight blur. If you scanned the image, try using the descreen filter on your scanner software.

u're right.. yeah.. but it must be possible.. that the photo looks much better... like the style on the front of the magazines.. u know..

i know that is difficult and i dont wanna find the "look-cool-button" but maybe a few tutorials :-D

>>like the style on the front of the magazines.. u know..

Then get yourself a light kit and hassleblad 4x4..

you can't take great pictures in the dark unless oyu are using a infrared photgraphy and that probably isn't what you are going for.

Basically retouching this image to make it look grainless will require bascially repainting the entire image.

This is however what you can do to try to make it better..

Make two copie sof th eiamge.. in the second one make it CMYK and take the black channel and paste it into a new image ile.

Then using the smudge tool clean it up by tracing over the lines in the black.

Then in the original copy.. duplicate the image and past it back into itself.. apply a soft blur until the grain is gone.

Then paste the black image on top of the blur and set it to darken.. now play with the opacity levels of the three layers until you get something you like.

I'd reccomend reshooting the picture, with a longer exposure.
If you want to fix the halting picture to an extend, you're left with noise reduction algos and stuff. My first suggestion is to seperate the colour information from the lightness, convert the picture to LAB mode. Then fix the lightness channel first.

sorry, dont understand.. lol, im a lil newbie sorry

Sorry to sound a little harsh, but Photoshop does have a help file, you know... just look it up, it's somewhere in there.
