noise allover the image .please help

Hello…. Have a huge problem and in need of help from you. Received images from the print shop. Some of ‘em came out good and some… well you see example of attached image. Noise allover the picture. I don’t know what caused it. So I have couple of questions. Where this noise coming from (humidity? Poor development? Bad film?) and second how can I get rid of it. Attached image is untouched (I didn’t even adjust levels) please help.

Try NeatImage from http://www.neatimage.com/

You can download the free version-- and it should help you take care of that noise problem quite effectively.

neat image is a great program, but i dont really think you need it here. i ran a gausian blur of 1 on the whole. i then added two adjustment layers, contrast and curves. then, on the main layer i ran Lum Frequencies to sharpen without adding noise back. 'Lum Frequencies' is Stroker's new plugin. you can find it in our software forum. after lum, you could run one more gausian or a median at a 3 or 5 if wanted.

and to answer your question of how you got the noise; you said 'film' so i know of two ways to get noise like this on film. one, the film has been sitting in the camera for a long time or was already old when bought, or two, the exposure was too dark when taken and the developer had to brighten it quite a bit to get the image. this is assuming a fairly standard film and not one of those 'grainy' films to begin with. and, in thinking about it, there may be a third way. if the developer is using digital printing to print your pics, it could have happened there as well, but i kind of doubt that one.

Neat Image will often do near miracles, but this seems to be one of those cases where there's just not enough separation between the image and the noise for it to decide which is which.

However, Cyber Cat, if you don't have it already then, yes!, you should get it.

As for the photo, I'm no expert but it seems by the thickness of the clouds that this picture was taken in very low lighting. Maybe that's the key. (??)


(oops, cross-posted with Craig, good thing we said the same thing!!)

Were you using a higher ISO film? Maybe that or possibly just from under exposure.
Neat Image should definetly help. In addition, you may want to try blurring the a and b channels in LAB mode. I adjusted the contrast a bit and found the water has a wonderful transition from blue to grey caused by the sky.

This is what I did with NeatImage-- and a minor color adjustment to make it pretty. I probably could have upped the noise reduction a bit more, but I was afraid I'd lose some sharpness in the waves, which I thought were quite nice.
