PS. perhaps we should move this to a "Dark Frame" thread so as not to
disturb the happy people

lol! Sorry Sues !!
What do ya mean? Do you know how many of us are happy about auto-DFS
relax ol'chap, note my use of "

lol! " in the above. sheesh!
but we have a misunderstanding in the offing here,
I know all about the tumbling hourglass and 2x15sec to do a 15sec exposure. I have done lots of astro pics at 60sec, each of which takes 2x60sec to record. no prob( except when freezing bits off taking pics of Orion in mid-winter !!! )
but terry said
" RAW files do have dark frame subtraction."
and I was asking how can we test for that in our panny.
The hourglass would tumble for 2 periods whilst dark frame processing the jpg, if or not it was
also darkframing the RAW as well ( or would it then take 3x periods to do that ? iyswim.
Now exposing raw alone and timing the periods involved seems not to me to resolve the matter because the RAW file includes an embeded jpg,,, errrm, or does it when taking raw alone ,,, I feel a test in the offing > > > ,,,
,,,
well, I never before did a raw alone, always raw+jpg, but yes it does take 2x15sec and it turns out that a jpg? (for evf/lcd display?) is generated and I am guessing will be embeded in the raw file. So, that didn't resolve anything !
