thats probably a bad title but i'm confused. i am scanning pictures and i wish to print them.

however when i open them in preview they look somewhat noisy. after a few seconds they snap to very clear and smooth.

when i print, will they be noisy? or will they be smooth? im afraid that only preview makes them look nice, other apps won't do the smoothing out part.

i have images but don't know how to uplad them.

Preview is loading every other line (or something like that) and then loading the missing lines. The image is unchanged. It just gets displayed faster. [Apply an appropriate amount of UNSHARP MASKING with Graphic Converter/Photoshop etc (Per PCPhoto use Amount 100%, Threshhold 4, radius 1). This sharpens the image considerably after scanning.] sam

I'm not 100% on this but, I think this has to do with Preview using Quartz's automatic antialiasing of images rather than interlacing. If you open an image in Photoshop it won't "smooth" out the image like Preview does.
