SUMMARY: When editing JPEGs, force Windows Live Photo Gallery 2011 to compress them in a way that keeps even more detail available.
Though you may not notice it, as you edit and resave photos in JPEG format with an editor such as Windows Live Photo Gallery 2011, image quality degrades. This is because JPEG is a "lossy" format, where compression (keeping the file size down) is achieved by discarding small amounts of image detail.
The more you edit and resave a JPG, the more detail you will lose, which is why you should convert JPEGs to a lossless format such as TIFF (and creating a backup copy!) before editing them. However, if you do not want to worry about this, Photo Gallery 2011 does a fairly good job at keeping most of the image detail available by compressing JPEGs at 98% quality. This can be bumped up even higher by doing the following, though it may increase the file size:
1. Click the menu button near the top-left of the Gallery window.
2. Select "Options" from the pop-up menu.
Or, just press Alt + F then O.
3. The "Windows Live Photo Gallery Options" dialog box appears. Click the "Edit" tab.
4. Underneath "JPEG quality", move the slider all the way to the right (High), or 100%.
5. Click "OK" to close the dialog box.
Note that before distributing a JPEG via electronic mail or over the web, you may want to reduce the image quality to decrease the resultant file size. You can reduce the quality down to 80%. Feel free to experiment; just make sure to keep a backup copy of your original in its high quality. And be sure to change this setting back after you are done saving JPEGs for distribution.
