Can someone explain this term? It seems that if I crop a photo 100% I would either end up with nothing or everything.

If you try to look at a full resolution image without downsizing it, you're viewing it at 100% size (which means that the image is not going to fit on a typical monitor screen from most modern cameras without scrolling).

So, sometimes a camera owner will want to crop a portion of the full size image and show it (so that someone can see what the quality would look like for that section of the photo if they were viewing the full size image on screen).

For example, if you cut out a 640x480 section from a larger 3000 x 2000 pixel image and did not downsize it, that 640x480 section of the original image would be a 100% crop (not downsized from the original 100% viewing size for that part of the image).

Jim has it right. A 100% crop is sorta like using a medium power loupe to look at a print. It show details that might contribute to the quality of the image, but cannot otherwise be seen.

Folks who spend a lot of time looking at those kind of images are known as Pixel Peepers - thought to get the merit badge in that category you have to look at 300% or higher. Sometimes there is something worthwhile to be seen, and often there is not.

Thanks... it makes sense now.
