what did you use as a lens? Do you have a VR lens?

stitched with Gigapan Stitcher 0.4.3864 The blur
is motion blur, you can see the seams between
adjacent frames, one sharp, one not.

Joel, congratulations on such a giant image! What
did you use to do the stitching? AP? With regard
to your questions about blurry images, all of the
things you mention are possible factors. I
don't know how much you know about photography
in general so please don't be insulted if I
suggest that you can determine the cause of some
problems by looking closely at your images. Eg
motion blur looks different to soft focus. Motion
blur can be fixed by shooting at higher shutter
speeds and/or ISO ratings. What I will say is that
there seems to be some support (from people who I
believe know what they are talking about) for the
idea that if you want to shoot gigapans like this
where everything is at infinity then you do *not*
want to use a DSLR. The reasoning is that if you
want lots of sharp pixels than you want a camera
with a small sensor i.e. a point and shoot. I
don't understand the physics myself, but I
used a super-zoom quite successfully taking shots
like this (not so big but everything at infinity)
before 'upgrading' to a 7D and a 50-500mm
lens. The latter may prove to be superior in the
long run, but it is *much* more difficult to use.
I'd suggest you stick to the SX10 and learn
its strengths and limitations unless you want to
spend a lot of money and a lot of time becoming an
expert on lenses and sensors. For more discussion
and examples of what I have managed see www.gigapan.org/gigapans/45223/
and do let me know if you come across examples of
other people getting good results with DSLRs and

castillonis - The Gigapan turned out ok. Maybe
I'm being overly critical of it, but as the
creator of it I'm quite aware of its flaws.
Some of the frames are blurry. It was a bit windy
during the shot so the Gigapan head was wobbling
and bouncing around a bit. This could be the cause
of the blurriness. It could also be movement from
the shutter button pusher rocking the camera. I
hope to have both of these problems resolved
before I start shooting Gigapans this summer.
I've had many, many problems with blurry
frames, so it's at the top of my list of
problems to eliminate. Getting the camera focused
was a problem at the beginning of my Gigapanning.
As it turns out, it is possible to have to camera
do the focusing in manual mode. It took me a while
to figure out the required settings and technique.
During post processing I ended up clipping the
highlights a bit. On the other hand, I did manage
to bring out more detail in the High Sierra
mountains in the background. I've also become
somewhat disappointed with the image quality of
the SX10IS. As you zoom in to the 1/1 point it
starts to break down. focus? jpeg compression?
lens sharpness? heat shimmer from the distance?
post processing? Would a DSLR such as my Canon
450D be better? It's a matter of responding to
the perceived imperfections so as to always
improve the product. There's always for
improvement. Maybe I'll make these
improvements and try taking this shot again.

This is great gigapan. How many shots?

Joel, this is a great panorama. It has
exceptionaly high image quality due to how large
it is and the fact that you captured it with a
point and shoot that is difficult to manually
focus. I was in the area this week and should have
made an attempt to meet up with you. Look forward
to your future gigapans : )
