Scanned slide resolution for Powerpoint?

[V. Bergmann]

I have a question regarding scanning 35mm slides for Powerpoint. I'm
scanning some slides for a PP presentation and am unsure of what resolution
to scan them at. The resolution of my notebook monitor & LCD projector is
1024 X 768 pixels. Should the slides be scanned at the same resolution (1024
X 768 ppi)? If this is the case, would I also still have to set the scanner
to scan at 72 ppi or higher? I'm new to this and appreciate any help.
Thanks in advance!

If a 35mm slide was 1 inch tall..... and you set the scanner to 72ppi, that
would result in 72 pixels per inch, so you would end up with a scan of only
72 pixels tall.

If a 35mm slide was 1 inch tall..... and you set the scanner to 300ppi, that
would result in 300 pixels per inch, so you would end up with a scan of 300
pixels tall.

If a 35mm slide was 1 inch tall..... and you set the scanner to 600ppi, that
would result in 300 pixels per inch, so you would end up with a scan of 600
pixels tall, which is closer to what you need.

Before I'd scan a whole batch of slides.... i'd do some tests with
brightness/contrast/gamma etc
