using digital photos in PP

[gary]

Hello,

I'm not familiar with powerpoint, but my friend uses PP to give talks and
lectures to groups of 100 to 200 people. He wants to use some of my digital
photos to spruce up his presentation, but he is a bit technically-challenged
and doesn't know what form I should submit them in.

I have a group of photos shot with Nikon cameras, some 12 Megapixel, some 6
Megapixel. The file sizes range from 2000x3000 pixels to 2800x4300 pixels.

My question is, what display resolution (and JPG quality) can powerpoint
use? Will higher-quality photos produce a better image on the projector
screen? Or is this dependant on the actual pixel-resolution of the
projecter that is used for the PP presentation?

thanks for any comments or advice...

Gary

Probably 1024 x 768 (JPGs or PNGs). Check out the following for more info:

You'll definitely want to downsample them. Start with the projector's max
resolution, set the PC up to match that, downsample your photos to match it
also.

My question is, what display resolution (and JPG quality) can powerpoint
use? Will higher-quality photos produce a better image on the projector
screen?

When you're talking about JPG, there are different compression levels; the
more compression, the smaller the file but the lower the quality. PPT won't
change this so whatever you feed PPT is pretty much what you get back.

Resolution is another factor in the quality equation but there's no real
benefit from feeding PPT more pixels than it can feed the projector.

I'd do some tests; downsample to 1024x768, the probable projector resolution
you'll work with; try different quality levels, view the images full screen at
1024x768 and choose the quality level that makes you happiest with the way your
images look.

Gary,

Generally - if you (or friend) are projecting the images... then you should
aim for the same resolution

If projector is 4000x2000 - then make images 4000x2000

I've never come across a projector that does 4000x2000..... so stick to the
most common resolutions....

see powerpoint tutorial on this very subject (forget dpi - think pixels)
