Re: [OM] Where's the V4.0 firmware upgrade for the E-M?

That seemed to work pretty well.  I've only ever tried focus stacking 
once and was so disappointed in the results that I've never tried it 
again.
It was 3 or 4 years ago so would have been done with the 5D.  I don't 
know which lens.  The neighbor's crabapple tree was in splendid bloom 
and I asked if I could cut off a small branch.  I cut off a piece about 
18-24" long and put it into a large vase with water in it.  I set the 
vase on a table on our enclosed porch... no wind.  I don't recall how 
many exposures I took or exactly how long it took (10-15 minutes at 
most) but the process didn't work.  To my utter astonishment the 
blossoms and tiny branches wilted so much during the shoot that the 
stitching software couldn't put them together.  At this point I don't 
recall if I was using Photoshop or Combine-Z.  In any case it didn't 
work.  One of these days I'll have to try again.
