I have seen a couple of posts that are the same, and no one seems to be able to answer the question. Everyone knows images get pixelated or blurry when zoomed in too much. Everyone also knows that you can zoom in more on higher quality images. The question I, and others are trying to get answered, is this: For the same exact image file...if zoomed in with Windows Photo viewer in Windows XP, the image just gets blurry the more you zoom in. However, if you look at the same exact image file in Windows Vista Ultimate...as you zoom in, instead of it getting blurry, it gets pixelated and blocky. Why?? Is there any way to get the windows picture viewer in Vista to act the same way as it does in XP?? I don't want to have to download a third party software program. I have plenty of pieces of software for editing images etc. But I use Windows picture viewer for quickly looking through photos.
