When selecting the file format JPEG the functions of the controls are:

this control. A higher percentage gives better quality but the file size
will increase. A lower factor will show some artifacts in the image but
the file size will be reduced.
•
Prev. quality : The JPEG quality level used for the preview is selected here. A higher
percentage gives better quality but the file size will increase. A lower
factor will show some artifacts but the file size will be reduced.
•
Prev. scale : This control defines the preview scale factor. Higher values result in
smaller previews; lower factors will produce larger previews but take
more time to send and display.
