    So my mom threw this tech problem at me, and I don’t know much about these things, so I thought I’d ask you. She and a friend of hers were out in a park, and the friend took a photo on her digital camera. The image had a blur in it, which also showed up in the jpeg file when she uploaded it to her computer, but the blur didn’t print – when they printed the file, it was just the scene without the blur. Does anyone have an explanation, or a suggestion about how to get rid of the blur?

    Thanks!

    She snapped a picture of a ghost!! icon_lol.gif

    Without seeing the actual picture, I'm just going to provide a wild guess..

    When you view a digital picture in full resolution, you can see a lot of details and some flaws. But when you print it out, it squishes all the pixels together. This usually causes the flaws to be less noticeable. And sometimes it brings back some clarity and sharpness to the rest of the image.

    Tell your mom to load a copy of the picture in an image viewer program and resize it down to like 50%. And see if the blur is still there.

    Some printers also come with their own 'cleaning up' software, often highly sophisticated ones. Same with how digicams can compensate automatically to different lighting conditions or how photoshop can get rid of redeye.

    And also, yeah, printing quality is often much lower than digital quality at full res. The pixelation and subsequent sharpening may have removed the blur.

    xrichx's suggestion is good. If all else fails, try rescanning the printed picture instead. Though the downside is you'll have a much lower res picture, you don't actually need a 4096x4096 digicam picture anyway. Unless you want everybody to be able to count all the pores on your face.
