[Digikam-users] jpeg compression again ( sorry )

Experiments have shown that if I use a jpeg compression
setting after minor edit ( eg curves only ) of about 90-95%
then the resultant file size is about the same as the
original.  Should I therefore be using that setting in order
to minimise quality loss ?  Certainly a setting of 100%
results in some excessively large files (which I would
rather avoid if I can).  What quality figure is generally
recommended, or is that a stupid question ?
