Wow! Thanks, David. So, the process is straight forward and simple when all the
parameters are met. Cool! I’m just back from an out-of-town project, and it’s
fun to see that what a manufacturer claims turns out to be true. Thank you.
Best regards,
Peter S.

Hi Philippe!
I didn't really expect anybody to be able to tell from the image, though some
will want to see it.
Trust me! It's poor! The problem is the obvious one, camera movement during
the series of exposures. I had no expectations of a good result, without a
tripod. The purpose of the test was to see just how easy it is to do... and
the answer is that it's bog simple!
I'm going to try it again (though not with Mt. Robson, as it's a 10 hour
drive from here - round-trip) with the tripod, and will report back, for
those interested.
But first, it has to quit raining.

Hi Peter!
Back in mid-June, you were asking questions about Hi-Res images in
various cameras.
Way back, in 2011, I posted this shot of Mt. Robson, taken in 16
separate images, with my old Nikon 200/4 Micro-Nikkor & stitched
together in HugIn.

At the time, it was the only way to get a high-res image - with the 16
photos yielding a 33.33mb image that was spectacularly detailed.
So, on the way home, last Tuesday, I decided to stop at Mt. Robson
again, and take a comparison photo, using the hi-res mode. It was
fun, and I'd never used the feature before!
The instructions say that the camera MUST be on a tripod. However, I
did not have my tripod with me, so I used my monopod, and held the
camera against a signpost.
The results were not exactly inspiring, but then I did not expect them
to be.

The point of the test was to see just how fast and how easy it is to
take a hi-res shot.
The latest 3.0 firmware update put the hi-res symbol directly into the
list of shooting modes visible in the viewfinder or back-panel
display. This makes it simple to select, whereas previously you had to
wade through layers of menu items.
And, you have to remember that because the sensor is being shifted by
the "motors" that normally run the image stabilization, IS is not
available in Hi-Res mode. (Since I was not using the recommended
tripod, this was a problem!)
Once I had the camera as stable as possible, I pressed the button.
The Hi-Res mode uses the electronic shutter (for less vibration and
more speed) and takes it's series of shots in well under a second (too
fast to measure). Then, the camera reports "busy", for another 4 to 5
seconds as it blends the images, and the dirty deed is done!
The result is a 49.939mp image that, had it been on a tripod, would
have been spectacular. As it was, it was "adequate", but that's my
fault, for not using a tripod, as instructed.
My other error (which I only learned about later) was that for best
results, Oly suggests f8 is the widest aperture to use. I used f7.1.
:-(
However, you'd wondered how difficult it was. The answer is that,
other than needing a tripod, it is so simple "a caveman could do it".
Swift and easy.
The only bit I've not figured out, is that Oly claims an 80mp image,
whereas I only got a 50mp one (8160x6120 pixels). Still, not bad from
a 20mp sensor! Oh, and the RAW image seems not to be a series of RAW
images which could be merged outside the camera, but a single, 20mp
image from the series. I suspect that for the whole range of raw
images & the 80mp image, you need to buy the new, rather expensive EM-
1x.
Still, for a free upgrade, I'm not complaining and I think the
landscape boys are going to be very happy with it.
Just thought you might like to know.
David.
