Re: creating digital panos

[Jesse Goff <jesse@xxxxxxxxxxxxx>]

3 parts for your equation: printing device, viewer distance, and output size.

you can make a great 40 ft billboard with a 40mb file.  I used to shoot
with the dicomed 4x5 scan back.  If a client asked for file larger than
50mb I would ask why.  9 out of 10 times they wouldn't need it.  I hardly
ever need a file bigger than 70mb but one can make a beautiful large pano
print with a 30mb file or even less.  I make great epson 6 color 4x20 inch
panos with 10 mb files.

tell me how large and what printer and what wall and I'll say what file
size you'll need for a reasonable image.

p.s. I don't think you should need more than 150mb avail. RAM. - unless you
are using a supercomputer.  if so i'd sell the supercomputer and buy a
roundshot. /
