DPI PPI or resolution. I want HIRES

This became an issue the other day when I found zooming to 3200 % wasn't
enough, and the text was just a blur.

I've seen Burt Monroy's lifelike paintings, and I know for fact that he's got
it down pat on how to zoom to a fly's eye ball, and correctly draw each and
every lens in the eye. And have it visible after zooming out ..

so 72 dpi,ppi isn't so great..
Yet that's what 99% of the images on the web are.. 72 DPI does more for zits
than all the face creams ever made..

I'll learn more today, but maybe someone would like to explain just HOW I can
zoom in and paint every facet of a fly's eye, and preserve those pixels after
zooming out to have the entire horse pasture in view and have the fly's eyeball
standing out as crisp and sharp as the hairs on the horses mane, and the
individual blades of grass. ?

You can see what I'm talking about with one of Bert's images of the adobe
offices and parking lot. You can see more than an acre of buildings and land,
and zoom to a car in the mid ground parking lot, and identify the license plate
by numbers..
CSI magic zoom.. No, it was a demo of the GPU reaction times. But more. Where
you could barely make out a license plate at full zoom out, when zoomed in the
plate was clearly readable.

For now I'm starting to use 300 DPI on the images I'm drawing. What I'm trying
for is drawing in hires. When I used the zoom bar at the top for 'original
size' vs the same drawing at 72 dpi , the 300 dpi was about 1 1/2 times larger
on screen than the 72.
I'll find out in a minute, but what could I expect drawing on a 3200 dpi image
? I have 2 gigs ram, and PS is allowed 60%.
I know I can always print the images at 72 dpi. But I want the POP graphics,
not the color blurs you get..
