Thanks Chuck and Tina
Very valuable input :-)
The thing is it never "pops" though when it is a NEF converted to DNG,
or even a plain NEF or an ORF - didn't occur either with the L1 and G1
RAWs
I'll try tomorow to shoot RAW and upload them without converting them
to DNG as I usually do, who knows ...
Thanks again
Amitiés
Philippe
