I have photos taken from two cameras, one in 72dpi and the other in 180dpi.
The photo sizes are the same, until I change the resolution in Photoshop on
the 72 dpi to 180. Then, the file size on the changed photos is huge. For
a slide show, do I need to resize the changed photos before putting them in
PowerPoint, or does PowerPoint care what resolution the photos come in at?
Thanks. CarolT

Don't think about resolution of your pictures. Think about pixels. What is
the size (in pixels) of your display. A typical projected display is 1024 x
768 pixels. If that is the size of your projected display, then there is no
need to have the pictures larger than that. When resizing in PhotoShop, look
for a setting to change pixels, not inches. When you put the pictures in
PowerPoint, you can adjust them to fill as much of the screen as you want.
