oh, it is weird, because I had turned off anti-ghosting, the panorama has a lot of ghosts. 
well, maybe I should upgrade my system to 64bit..

I know that but if I compression off the image size, the quality of pano will decrease, isn't it?
I dont know the zip compression of tiff images, but the LZW compression is lossless, so using the LZW your tiff panos are smaller in size (mbs on harddisc) without loosing imagequality.

ethanchen, are you actually comparing filesizes of JPEG and TIFF files?!? I hope that's some kind of a mistake, otherwise it shows some glaring omissions in your understanding of the subject...
Of course JPEGs will be smaller than TIFFs - they are LOSSY compessed files. So, open your 42 JPEGs in PS, save them as TIFFs and THEN compare the total size vs. the one of the composite panorama!

Hello ethanchen
You can calculate the uncompressed (maximal) filesize vor RGB-TIF's easy: Pixel H x V x 3 Byte (for 8bit color) or H x V x 6 Byte (for 16bit color, if You have a HDRI).
If your pano is 300 MPixel, a uncompressed TIF has 900 Mbyte.
For TIF compession as LZW or ZIP is always a good idea ;-)

if uploading images to the forum is a challange...
than creating panos will be a very high mountain to climb ;-))
