[DarkHorse]

OK, so ive spent two years-spring to fall in alaska,
a year in Texas, a year in AZ, and ect,ect,
ive got critters,flowers coming out the ports of my computers hardrive,
and now i want to put togeather a book,,,

I have:

Macbook,the little aluminum one,
Dell 2209WA monitor,
Canon pro 9000

when i print out pics, i tussle around getting the colors/contrast,ect,ect right,
but i do get there,,,

so im wondering,

1-before i send my converted- (I think Jpegs)- to a company,
should i get a monitor calabration tool??

2- what happens if i send them 50 pics for a book and it comes back and the pics do not look like i see or want them?

3-
how does one set up the pics,,color/contrast/ ect ect,,
for shipping the-Jpegs? to the company
