Thats neat to see a little piece turn into a complete treasure. Seems like your in an area of larger points verses the true bird points we have seen in the past.
Here's a piece of related trivia that you as a movie producer already know. Video eats up a lot more pixels faster than stills...
Badger & I recently mused over this matter...probably as little as 5 years ago the very small sized SD format was fantastic at 250 megabytes ...then the 2 Gig model
that I have been using gets 2000 stills on it.
Based on this highly technical discussion, my next visit to Walmart I checked the camera area....to my surprise I found this very same physical sized card at
SIXTY TWO gigabytes ! ( 62G )
Thats enough for a Cecil B DeMille sized production !
