In the original, the sky is OK, only the plane really needs any work. Mask the sky, feather the mask slightly to avoid a hard edge, then the correction you apply will affect the plane only and avoid bringing out the grain in the sky.

Of course this is a correction to a problem in the original - much better to avoid the problem in the first place. The easy answer is slow speed film, but I know this isn't always practical.

My tip is, if you must use fast film, then it is important to get the exposure just right - if you're using print film, slight overexposure is safer than under exposure. At J.net sizes, a well exposed 400 ISO shot should show little evidence of grain.

From the looks of it, the original is just slightly underexposed, hence the excessive grain.

Cheers,

Colin
