I just cant work this out!
When I insert an image into a Powerpoint slide, it is automatically reduced with less resolutions. I know the default ppi is 220 but how does that work out, for example, I have inserted a picture with 5184 x 3456 resolution
and it ended up reduced to 1114x742, and another picture was 2984 x 2238 and ended up 990 x 742. so I guess it it not just a case of dividing by 220
Thanks
