Hi
This is all due to resolution. You can change an images DPI, but that in essence is scaling the image.... and bitmaps (all photos are bitmap based (made up of pixels) so they are NOT scaleable. You can scale them of course but they lose quality as you scale them.... so you can't really change the DPI (or PPI - Pixels per Inch) since it manipulates the image. You can lower it, but you can't increase it. And once an image is optimized as a GIF, JPEG, or PNG it is 72 dpi. So unless an image has a high resoultion with a LOT of pixels.... zoooming in will always show pixels and will probably look blurry. So whatever size you need will look good at its ACTUAL size. So export to the size you need, knowing you should be starting off with the highest resolution possible - (you can scale DOWN, but you can;t scale UP without pixelating or losing quality in your image) and then just make sure you present it, post it or view it in actual size. Hope this helps! mark Hope this helps!
