Congrats Gerald. Thanks for raising the bar -
another challenge. Big question - Power Source
& image storage Did you have an external
power source for the Canon 7D? What about the Epic
Pro? - several batteries, or did you have an
external power source for it, too? How did you
store the images as they were taken? large CF
card(s), or directly onto an external drive? .jpg?
Nice work! Thanks for trying out ICE at
jdughi's suggestion. As one of ICE's
developers, I'd like to know more about the
crash. If you'd like to help, please email us
(hdview at microsoft dot com) or post to the ICE
orums/112.aspx ) with some details:
was ICE stitching or exporting or publishing; how
much progress did it make; did you get an error
code; was it 32-bit or 64-bit ICE; what OS are you
running; how much memory and temp disk space?
Thanks! --Eric Microsoft Research
Thanks for the explanation. Now I have understood
Hi hschulze - The 220 degree width was a
guestimate as I had to enter it when geo-coding.
Fortunately, I took a screenshot of the render
preview in Autopano Giga which I've just
checked back on. The FOV given by Autopano Giga is
243.3 x 46.19 degrees, which I will update in the
description here now. Not sure how you're
calculating a 240,000 pixel width - are you taking
into account the crop factor of the sensor? The
only place I can see the pixel dimensions is in
the render preview (obviously I can't open
this anywhere), which reports a width of 472,603
pixels. Assuming you've missed off the crop
factor, and 240k for 220 degrees would be correct
if it were full frame, 240k/220*243.3*1.6 would
give a width of 425,000 pixels - 90% of the number
reported by Autopano Giga. Presumably the
projection of what is actually a 3-dimensional
spherical image onto a flat plane is accountable
for the additional 10%.
The physics does not fit here. The sensor of the
7D is known. At 220 degrees HFOV possible only
240,000 pixels are horizontal. 44.88 Gigapixel
mean height of 180 degrees. There are now only 45
degrees. What is wrong? Sorry for my bad english.
Among the other BIGGEST THINGS Dubai just got the
biggest gigapan. This is finlly something worth to
see. You did a nice job. Hope will repeat the
similar at the better weather. What is dimension
of the pano in pixels. After this Photoshop should
think of its limitations, publishing CS5. After
this thinking of what are the limitations of
Hi Kilgore661 - Thanks for the kind comments.
I've added basic PC spec, and also geo-coded.
An astonishing achievement in its own right, but
you seem to have done this on your own unlike
other world records that used teams of people
iirc. What were the specifications of the computer
you used? Also, please geocode!
jdughi - I tried stitching this with ICE, but
despite MS's claims for its ability to deal
with practically unlimited size panoramas, it
Only because on this scale it makes a bit of
difference, change your ISO increments to be 1:1
stops. Any sensors other than the EOS-1 series
sensors only have native stops of 1:1. All other
Canons use processing to boost up or down from the
native stop. In this case, ISO 400 processed to
look like 320.
i'd love to see this stitched using MSR ICE
and uploaded to the Photosynth site. The viewer is
The Canon 500mm f4 is an excellent lens and it
works well with the 1.4x teleconverter at f11. You
need to enable mirror lockup in your camera at
that focal length. I completely understand the
resource issue. I rented the Canon 500mm f4 for 14
days and it cost me a pretty penny. You should
definitely talk to Canon to see if they would loan
you a lens. The 500mm does not have vignetting
issues like the 100-400mm. The 300mm is also a
very nice lens.
Hi Castillonis - Oh that I could afford a 300mm
f/2.8! I can only work with what I have, and I
just do this for fun. When I do have another go -
which probably won't be until October or
November (the air quality here will be terrible
until then), I'll probably look to borrow a
500mm f/4.0 from Canon Middle East and do a 360
degree pano from the crows nest on a crane on top
of the building - I reckon that should deliver
something close to 100GP. These images were taken
at f/11 1/800th at ISO 320. You're right - it
is important to stress that this is a purely
technical exercise, and it's also worth
mentioning the huge effect the high temperatures
have on image quality due to the heat haze. If
only the Gigapan Pro had come out 6 months
earlier! Until November then ;) ...
Congratulations on capturing, stitching, and
uploading this monster image. I would love to
learn more about how you overcame different
challenges. In the future I would use a 300mm f2.8
with a1.4x teleconverter stopped down to at least
f8 to f11. The lens that you used usually exhibits
significant vignetting that is difficult to
rectify using the peripheral illumination on the
Canon 7D. It is also good that you immediately
communicate that this is not an artistic image and
that the atmospheric conditions are not the best.
Though if you do not perform this excercise you
would not be ready when you have that golden
opportunity. Great job and I would love to hear
from you about your experience doing this : )
I believe this is a new world record for pixels!
The previous was those of Paris 26 Gigapixels www.paris-26-gigapixels.com/index-
may be I am wrong ... But it is a world record
(2010.05.01) on gigapixels?
Great shot Gerald, a really impressive view. Pity
your not able to fine tune the image in KRO format
:( maybe one day.
Give some specifications on the equipment used and
the stitching details. Great shot...we hope you
had sufficient bandwith during the upload! Rather
poor air quality by the look of it.
