Title: 3.2 GP
Post by: wolfnowl on August 31, 2012, 03:22:35 am: What? You're still talking about MEGA pixels? ???

Mike,
Thanks for the article. I read it [too] quickly and thought what's the fuss with 3.2 MP images! Re-reading the article and I then realized that it was 3.2 GB!!! I guess that we'll need some pretty powerful computer to handle that kind of images, Lightroom 4.x won't cut it.

And how many assistants do I need to carry the memory card?

One decent exposure bracket and you'd better will it to your grandchildren.

Of course, you can!

I bet that you'll need a "cohort" of assisants. With that pixel count, memory cards are out... we need hard drives.

Stitching has its limitations, but it doesn't require a medium-sized truck and a crane to carry and set up your gear. That's an important advantage for me, since I much prefer to drive a smaller vehicle. My wife also appreciates the lower cost.

You understate the magnitude of the task. It's 30TB of data per night.

Thanks, that was a typo.

For comparison sake, this past weekend, I copied about 2 TB of data to new drives on the same server. The server is a PowerEdge 2950, which is a nearly state of the technology, enterprise class server, and it uses RAID5 drive config and 7.2K RPM SATA drives. This “mere” 2 TB of data took nearly 2 days for a complete copy. These folks are producing 30 TB of data storage (15 times what I worked with) per night suggests a whole lot of parallel processing and/or a new generation of processing hardware, or perhaps both.
