Discussion on 360-fish-eye-team

[Fraz]

Just a quick thought, ran a few numbers and at 110,000 feet you would
need a field of view of about 170 degrees to capture the whole earth
in a single shot. And that would be with a perfectly centered shot.

I cant figure out how to add to the other discussion, but I think that
a DSLR camera is really what we need for this job. the nikon P5000 is
only capable of producing images of 20x30 in. If we are going to try
to get 3 images together, I think that we might want the ability to
produce large poster size images of great quality. I found that "at
17.1 oz. Rebel XT, currently the lightest digital SLR on the market,"
on http://www.digitalcamerainfo.com/content/Canon-Digital-Rebel-XT-Digital-Camera-Review-/Conclusion.htm
and there is a 20mm lens for it that weighs in at 14.3 oz

9 out of 10 people will tell you that canon has the highest quality
lenses, a big factor in image quality. Although using this camera/
lens comb will be more costly, I think that if we have enough
"room" (can take the weight), then our images will be much more
impersive.

OK, so I called Nikon to get a recommendation on memory cards and this
is what I found out:
- Use SanDisk or Toshiba (he Strongly recommended SanDisk)
- Make sure it is SDHC
- Do NOT go over 4G
- 4G cards start at $100 and go to $140 for the most durable.

Also, He said that if we are using a 2G card to make sure it is high
speed (10MB/s or 20MB/s). Panasonic is also listed on p. 91 of the
User's Manual as being an acceptable brand.

Justin and I need input on the time interval that we want to take pics
at.
-For a 2G card we get approx 400 images at the highest quality. for a
rise rate of 1000ft/min that is 7200 sec of fly time if we get to
120000ft. that corresponds to 1 pic every 18 sec or 300ft.
-For 4G we get approx 800 images, which is i pic every 9 sec or every
150 ft.
That is if we take pics continuously the whole way up.
