100% cropping question

What does it mean when you see "100% crop" associated with a blown up part of a photograph? It usually looks about 10% or less of the original. Presumably it relates to the pixel count in some way?

M, yes, if your screen was 1000 pixels in the long direction and 500 in the short, when you viewed a foto at 100%, that's how many pixels you would see of the foto.
If your screen where really big and of high quality, say 5000x3000 pixels, and that was the size of your fotos, you would always be seeing them at 100%.
100% is important because you are viewing(pixel peeping) at the most undistorted reproduction that your screen can present to you, since it is not interpolating the pixels in any way for you to view.
If your screen is 1000 pixels across and your foto is 5000, then on the full screen you can only view 1/5 of the pixels at a time and your viewing software is picking which you will be seeing and not you.
I'm sure it's way more complicated than that, so the real experts will have to chime in. They're probably all out shooting today, but here it's raining.
M, if that's to confusing, let me know and I will rephrase it differently. Good luck and happy shooting.

OK Thanks. Presumably when you see it quoted in a magazine the same applies - they print the cropped piece so the print dot resolution is the same as the pixels in the photo?

Hmmm, M, I think your throwing curve balls now. I've never given that much consideration, since most of the comparisons we see are on digital screens.
Let's not forget that dots are round with spaces between them and pixels are squarish to rectangular. Nor do I think most publications can do that high of a dot count, to actually simulate a photo at 100%.
Using native resolution on a digital monitor versus printed material seems almost like trying to mix oil and water.
M, I guess what it comes down to is that I don't actuall have any kind of accurate or reliable info for that comparison. Hopefully somebody here is in the publishing business or at least a real graphic artist that could give us something accurate.

The easiest way to see this is to open a photo editor, select a photo and change the View to 100%.
Like said above, if the photo is an 8x10, but your screen is only 4x5 then your editor will shrink the photo to match the size of your screen. If you change the View to 100% you will see the photo at the original size the camera took it at although not all of it will be visible on the screen unless you scroll.

The above is the best definition I can find. Basically, it is viewing a selection that was taken at full size - 100%. Please consider going - others have a problem with calling it 100% crop.
