RE: creating digital panos

["Lee, Martin (Ex AS01)" <MLee@xxxxxxxxxxxxxxxx>]

well for starters I am not going to be printing it - I lack the necessary
hardware.
I just want an image that will fill the screen (vertically) and scroll
horizontally.
so 1024 pixels height * ratio of about 3:1 = 3072 - covers about 40%
horizontal size of the ptools output image = 7680

I think I'll try a smaller image size - I stuffed up the calculation somehow
last time....sorry to bother you guys/gals.

thanks for the information anyhow,
	MARTIN.

PS: good tip about the roundshot...however I am not using a supercomputer
(although I wouldn't mind it). Just my PC at work...I experiment a bit with
digital imaging in my spare time.

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. /
