Hi,
a) how has you saved it. As JPEG, portable network graphics,
in a notebook, as encapsulate postscript
b) the input images where JPEG, that mean lossy compressed by
a typical ratio 1:50. Usualy one avoid lossy compression at all
especial when you work/"image process" the images because every
evening when you save you work the lossy compression will reduce
the quality of the image. Lossy compression is optimized in
a way that a human eye will not see it. Any computer algorithm
that work with the images will make the artifacts visible.
c) save the last image of you processing chain a JPEG. But keep in
mind lossy compression is the week version of "trash it"
Regards
Jens
