Re: Does editing compress my JPG:s?

["Antti Ahonen" <aahonen gmail com>]

I know that the originals are not affected, but if I export a batch of
pictures, the ones I have edited are compressed. I allways try to keep
all compressing in minumum when I edit my pictures.

Would it be possible to have an adjustment for the amount of compression used?
