Did you mean MB rather than GB?

Kind of wondering what kind of image would be 30GB... :)

Thanks. Found info on that file format:

Pages 14 onward give the info. Seems like it's a variation of TIFF, in tiled format.

Main tile (image) size is 120k x 80k. That's huge!

29GB when saved uncompressed. I'd hope most applications would use the optional compression features. :)

This was 360 degree mosaic, about 100kX100k
