[ale] OT: megapixels

[Josh Freeman]

IT all gets down to what resolution I want. "Screen resolution" can be
assumed to be fairly low: 72 pixels per inch is fairly common, and I
think this is what Gimp assumes. Digital photographs have to be printed
at a much higher resolution to look good on paper. When I was working on
the Georgia Tech newspaper, I think we scanned all our photography at
around 250 pixels per inch, and I think this is what the yearbook uses
now.  I can get a pretty good 8"x10" from my 2 megapixel camera.  This
camera is all I need for taking pictures at parties and such as that. I
would want something along the lines of a Nikon D-100 (6 megapixels) or
the new Kodak 14 megapixel job if I was 1)independently wealthy and 2)
doing serious portrait or artistic photography.


Megapixels are like memory. Get all that you can afford. You will always
find a use for them.
