If the original data already are in JPEG you neither gain nor loose
anything
when further converting those to TIFF for processing.
JPEG reading **should** be independent of the reader used, it should
neither
introduce or remove extra artefacts (as sometimes is the case with MPEG),
small differences between applications might exist, due to rounding errors.
I do not know how "good" the ImageJ JPEG reader code is, there was an issue
that
the *writer* code seemed a bit too lossy, even at the highest quality
setting.
