Note that if the data is simply viewed, and not modified in any way, the picture corresponding to the EXIF data is also left unmodified. However, if any data was changed, the picture will have to be overwritten, and in case it uses a lossy format, such as JPEG, its quality may decrease. To avoid it, make sure that the quality slider control is set sufficiently high (at or above the previously used quality value to save the file).

|
| JPEG Quality: | If the picture for which this EXIF information has been edited is saved in JPEG format, this slider determines the quality with which to re-save the picture in order to apply any EXIF changes. Note that if EXIF information has only been viewed, but not changed, the original picture will also be left unmodified.
|
