Print issues.... hohum.... The whole issue with print will be the amount of raw image data u have to output to print. If u have 2 shot hemi with say diameter of 1600 pixels as jpg, this should equate to approx 800kb of compressed jpg data per hemi. This in turn will let you output a photo of around 2 x 10x15 cm maybe even 2x 15x18 cm . This will be the max output for print you'll achieve for 300dpi as you don't have anymore data. If you do a 3shot hemi and actually use a method to increase ur data input* u'll be able to generate a larger sharper image.
note: to upgrade from 72dpi to 150 dpi u'll decrese image size by 4. To upgrade to 300 dpi u'll see image six decreas by a factor of 16. (Or so I'm told by our print guys) To produce large scale pano images, u'll have to revert to multiple wide angle lens shots and use other pano software to stich (there's lots of stuff out there). Most guys I know wil take approx 24-36 DSLR (Or even use film/slide film and scanners) shots and use output RAW images to stich in software of choise. These files are huge 200, 300...800 MB... just so that they can produce poster and larger size panos.
*(when in portrait mode: zoom in until top and bottom of image touch viewer edge. This will enable u to have an image approx 140deg across and 183 deg in height = u use more of ur camera ccd chip = more basic raw data which is also sharper. I can get an image with my cp4500/fc-e8 combo which is then approx 2100px in height instead of say 1550px when only useing 2 hemis. This means I use around 85%-90% of ccd chip instaed of just around 50% on single hemi)
------------- If I only had an hour to chop down a tree... I'd spend 45 mins sharpening the axe.
